  • Autocomplete server-side implementation

    - by toluju
    What is a fast and efficient way to implement the server-side component for an autocomplete feature in an html input box? I am writing a service to autocomplete user queries in our web interface's main search box, and the completions are displayed in an ajax-powered dropdown. The data we are running queries against is simply a large table of concepts our system knows about, which matches roughly with the set of wikipedia page titles. For this service obviously speed is of utmost importance, as responsiveness of the web page is important to the user experience. The current implementation simply loads all concepts into memory in a sorted set, and performs a simple log(n) lookup on a user keystroke. The tailset is then used to provide additional matches beyond the closest match. The problem with this solution is that it does not scale. It currently is running up against the VM heap space limit (I've set -Xmx2g, which is about the most we can push on our 32 bit machines), and this prevents us from expanding our concept table or adding more functionality. Switching to 64-bit VMs on machines with more memory isn't an immediate option. I've been hesitant to start working on a disk-based solution as I am concerned that disk seek time will kill performance. Are there possible solutions that will let me scale better, either entirely in memory or with some fast disk-backed implementations? Edits: @Gandalf: For our use case it is important the the autocompletion is comprehensive and isn't just extra help for the user. As for what we are completing, it is a list of concept-type pairs. For example, possible entries are [("Microsoft", "Software Company"), ("Jeff Atwood", "Programmer"), ("StackOverflow.com", "Website")]. We are using Lucene for the full search once a user selects an item from the autocomplete list, but I am not yet sure Lucene would work well for the autocomplete itself. @Glen: No databases are being used here. When I'm talking about a table I just mean the structured representation of my data. @Jason Day: My original implementation to this problem was to use a Trie, but the memory bloat with that was actually worse than the sorted set due to needing a large number of object references. I'll read on the ternary search trees to see if it could be of use.

  • Why wont this sort in Solr work?

    - by Camran
    I need to sort on a date-field type, which name is "mod_date". It works like this in the browser adress-bar: http://localhost:8983/solr/select/?&q=bmw&sort=mod_date+desc But I am using a phpSolr client which sends an URL to Solr, and the url sent is this: fq=+category%3A%22Bilar%22+%2B+car_action%3AS%C3%A4ljes&version=1.2&wt=json&json.nl=map&q=%2A%3A%2A&start=0&rows=5&sort=mod_date+desc // This wont work and is echoed after this in php: $queryString = http_build_query($params, null, $this->_queryStringDelimiter); $queryString = preg_replace('/%5B(?:[0-9]|[1-9][0-9]+)%5D=/', '=', $queryString); This wont work, I dont know why! Everything else works fine, all right fields are returned. But the sort doesn't work. Any ideas? Thanks BTW: The field "mod_date" contains something like: 2010-03-04T19:37:22.5Z EDIT: First I use PHP to send this to a SolrPhpClient which is another php-file called service.php: require_once('../SolrPhpClient/Apache/Solr/Service.php'); $solr = new Apache_Solr_Service('localhost', 8983, '/solr/'); $results = $solr->search($querystring, $p, $limit, $solr_params); $solr_params is an array which contains the solr-parameters (q, fq, etc). Now, in service.php: $params['version'] = self::SOLR_VERSION; // common parameters in this interface $params['wt'] = self::SOLR_WRITER; $params['json.nl'] = $this->_namedListTreatment; $params['q'] = $query; $params['sort'] = 'mod_date desc'; // HERE IS THE SORT I HAVE PROBLEM WITH $params['start'] = $offset; $params['rows'] = $limit; $queryString = http_build_query($params, null, $this->_queryStringDelimiter); $queryString = preg_replace('/%5B(?:[0-9]|[1-9][0-9]+)%5D=/', '=', $queryString); if ($method == self::METHOD_GET) { return $this->_sendRawGet($this->_searchUrl . $this->_queryDelimiter . $queryString); } else if ($method == self::METHOD_POST) { return $this->_sendRawPost($this->_searchUrl, $queryString, FALSE, 'application/x-www-form-urlencoded'); } The $results contain the results from Solr... So this is the way I need to get to work (via php). This code below (also on top of this Q) works but thats because I paste it into the adress bar manually, not via the PHPclient. But thats just for debugging, I need to get it to work via the PHPclient: http://localhost:8983/solr/select/?&q=bmw&sort=mod_date+des // Not via phpclient, but works UPDATE (2010-03-08): I have tried Donovans codes (the urls) and they work fine. Now, I have noticed that it is one of the parameters causing the 'SORT' not to work. This parameter is the "wt" parameter. If we take the url from top of this Q, (fq=+category%3A%22Bilar%22+%2B+car_action%3AS%C3%A4ljes&version=1.2&wt=json&json.nl=map&q=%2A%3A%2A&start=0&rows=5&sort=mod_date+desc), and just simply remove the "wt" parameter, then the sort works. BUT the results appear differently, thus making my php code not able to recognize the results I believe. Donovan would know this I think. I am guessing in order for the PHPClient to work, the results must be in a specific structure, which gets messed up as soon as I remove the wt parameter. Donovan, help me please... Here is some background what I use your SolrPhpClient for: I have a classifieds website, which uses MySql. But for the searching I am using Solr to search some indexed fields. Then Solr returns an array of ID:numbers (for all matches of the search criteria). Then I use those ID:numbers to find everything in a MySql db and fetch all other information (example is not searchable information). So simplified: Search - Solr returns all matches in an array of ID:nrs - Id:numbers from Solr are the same as the Id numbers in the MySql db, so I can just make a simple match agains every record with the ID matching the ID from the Solr results array. I don't use Faceting, no boosting, no relevancy or other fancy stuff. I only sort by the latest classified put, and give the option to users to also sort on the cheapest price. Nothing more. Then I use the "fq" parameter to do queries on different fields in Solr depending on category chosen by users (example "cars" in this case which in my language is "Bilar"). I am really stuck with this problem here... Thanks for all help

  • Is SEO knowledge important for web developers?

    - by splattne
    Looking for some SEO (Search engine optimization) questions on Stackoverflow, I saw ambivalent reactions to these questions. Some were closed as "not programming related" or were downvoted, others were answered and got upvoted. It seems that many developers think SEO was something "dirty" or belonged in the realm of spam. IMHO designing for search engines and practising SEO techniques adds important value to the final product like, for example, a good user interface. Should SEO really be left to specialized non-programmers? Shouldn't web developers have profound SEO knowledge? Or is it okay to apply SEO as a post-development process?

  • Recommended Tutorials for php mysql and graphs

    - by Vinit Joshi
    I need help to find a tutorial or anything to help me create a comparison chart. The user is able to search for device names. The information about the device names is in a drop down box dynamically added from the database. I want the user to be able to select two separate devices and view the devices information plotted onto a graph. I'll be grateful for keywords that I can search for or any tutorials that will help me to carry on with this task. Currently on my screen I can see the data that has been inserted into the database. This data is placed inside a table. I have so far used xhtml, php and mysql. I've tried to make the question as clear as possible so sorry if it does confuse anyone.

  • C# failing LDAP queries

    - by jpkomick
    I'm trying to access an LDAP directory via the SearchRequest object in C#. I can make the same calls via an LDAP library running in and iPhone app, as well as directly via a terminal session. However, the C# queries all seem to fail. var search = new SearchRequest("ou=calendar,dc=ualberta,dc=ca", "term=*,course=094398,class=*", System.DirectoryServices.Protocols.SearchScope.Subtree, attributeLst); This returns a list of terms for the course calendar. However, making the following calls won't return results for specific courses var search = new SearchRequest("ou=calendar,dc=ualberta,dc=ca", "term=1330,course=094398", System.DirectoryServices.Protocols.SearchScope.Subtree, attributeLst); The attributeLst object has proper attribute names included, but the query always returns with zero results. Any suggestions anyone has would be greatly appreciated. Thanks.

  • ASP.net Text Box Enter button pressed hell

    - by Morgeh
    Basically I have an asp.net website with login and search pages. Currently, I have no idea why, when ever a user hits enter in either of the login text boxes (user name/password) or in the Seach text box, the website is redirected to the default page. I have no idea why this is happening, I've tried setting defaultButton on both the panel containing the search and the login panel but that doesnt seem to work. I've also tried catching the key press event with javascript which isnt working either. I have no idea what event is being fired and why, or why it seems to override everything I try to do. Anyone seen anything like this before?

  • UISearchDisplayController's full-screen background intercepts touch events in iOS 7

    - by tba
    I have a UITableview that doesn't take up the whole screen (screenshot). Everything worked fine in iOS 6. But in iOS 7, when the user searches, the search result table takes up the whole view (screenshot). To fix this, I tried setting the frame manually as described in this answer. The appearance is now correct (screenshot), but now the "<" button in the top left doesn't receive tap events when the search results table is displayed. It seems the searchResultsTableView is adding a full-screen background view that is intercepting touch events. To prove this, I added this code to didShowSearchResultsTableView: controller.searchResultsTableView.superview.backgroundColor = [UIColor blueColor];` This screenshot confirms my hypothesis. How can I fix this to allow the "<" button to receive tap events? I want to avoid modifying controller.searchResultsTableView.superview so that my change doesn't break in future versions of iOS. And what change in iOS 7 caused this behavior to start happening?

  • noindex, follow on list views?

    - by Fabrizio
    On one of our client's website we have lot's of list views with links to detail views. (Image a blog with the posts overview and the single pages). The detail views don't change, but the list views will change when new items come up. The pages displaying the list view don't contain any other valuable content. So my question is: Does it make sense to define meta "noindex, follow" on the list view pages (and of course "index, follow" on the detail views) to prevent search engines to point to the list views when the keyword is found in the title or teaser of the list view. By the time the visitor clicks on the list view search result it might have changed and the content is not visible anymore, whereas if he goes directly to the single view he will definitly find what he was searching for? Related question: The startpage also contains mainly a list view. Is it a bad idea to have the start page not indexed? Any SEO gurus here? :) Thanks, Fabrizio.

    - by jquery n00b
    I'm trying to replace all submit buttons with a span so cufon will work. The input still needs to be there so have done some css to hide it and overlay to span on top. My issue is getting the value from the input tag is proving quite diffcult. The code below gets the first input value (being 'search' from the search box at the top of the page, and then puts that value into all the spans, even for buttons that have different values (eg: send). This is a .NET page so the whole page is wrapped in one form tag. Any help is greatly appreciated. jQUERY: jQuery(document).ready( function() { jQuery(".button-wrap input.button").each(function() { var values = jQuery(".button-wrap input").attr('value'); jQuery(this).before("<span class='input-replacer'>" +values+ "</span>"); });

  • How can I find a package?

    - by Roman
    In my code I have the following statement import com.apple.dnssd.*; and compiler (javac) complains about this line. It writes that the package does not exist. But I think that it could be that "javac" search the package in a wrong place (directory). In this respect I have two questions: How can I know where javac search for the packages? I think that it is very likely that I have the above mentioned package but I do not know where it is located. What are the typical place to look for the packages?

  • Google maps spatial reference system

    - by JavaRocky
    What is Google map's spatial reference system using when you enter a lat, long into the maps search bar? I've found hints that it might be WGS84 but after converting to that coordinate system, nothing shows up when i paste the coordinates into the google maps search box. I am converting from GDA MGA 56. Sample: Input MGA56 coords: 336301, 6253363 Expected WGS86 coords: -33.8473340793201, 151.230631835944 I get: 16834916.928327594 -4008321.1020318186 Spatial coord systems: EPSG:28356 for MGA56 EPSG:900913 for WGS86 (google maps) I am using geotools to do the transform: CoordinateReferenceSystem crsMga56 = CRS.parseWKT(mga56); CoordinateReferenceSystem crsGmaps = CRS.parseWKT(gmaps); Coordinate coordinate = new Coordinate(336301, 6253363); Point point = new GeometryFactory().createPoint(coordinate); MathTransform transform = CRS.findMathTransform(crsMga56, crsGmaps); Geometry geometry = JTS.transform(point, transform); I know the transform is not correct, as when i use an online tool it gives me the correct coords. http://www.environment.gov.au/cgi-bin/transform/mga2geo%5Fgda.pl?east=336301&north=6253363&zone=56

  • How to merge data from two separate access 2007 databases

    - by DiegoMaK
    Hi, I have two identical databases with same structure, database a in computer a and database b in computer b. The data of database a*(a.accdb)* and database b*(b.accdb)* are different. then in database a i have for example ID:1, 2, 3 and in database B i Have ID:4,5,6 Then i need merge these databases data in only one database(a or b, doesn't matter) so the final database looks like. ID:1,2,3,4,5,6 I search an easy way to do this. because i have many tables. and do this by union query is so tedious. I search for example for a backup option for only data without scheme as in postgreSQl or many others RDBMS, but i don't see this options in access 2007. pd:only just table could be have duplicate values(I guess that pk doesn't allow copy a duplicate value and all others values will be copied well). if i wrong please correct me. thanks for your help.

  • Strange JavaScript Regular Expression Behavior

    - by Kiwi
    I'm getting different behavior from a regular expression in JavaScript depending on whether or not I declare it using literal syntax. Using a extremely simple test HTML file: <html> <head> <script type="text/javascript"> var s = '3'; var regex1 = /\d/; var regex2 = new RegExp('\d'); alert(s.search(regex1)); // 0 (matches) alert(s.search(regex2)); // -1 (does not match) </script> </head> <body></body> </html> The regular expression declared with literal syntax (/\d/) works correctly, while the other (new RegExp('\d')) does not. Why on earth is this happening? I'm using Google Chrome 5.0.375.70 on Windows Vista Home Premium, if that's at all helpful.

  • Optimize MySQL query (ngrams, COUNT(), GROUP BY, ORDER BY)

    - by Gerardo
    I have a database with thousands of companies and their locations. I have implemented n-grams to optimize search. I am making one query to retrieve all the companies that match with the search query and another one to get a list with their locations and the number of companies in each location. The query I am trying to optimize is the latter. Maybe the problem is this: Every company ('anunciante') has a field ('estado') to make logical deletes. So, if 'estado' equals 1, the company should be retrieved. When I run the EXPLAIN command, it shows that it goes through almost 40k rows, when the actual result (the reality matching companies) are 80. How can I optimize this? This is my query (XXX represent the n-grams for the search query): SELECT provincias.provincia AS provincia, provincias.id, COUNT(*) AS cantidad FROM anunciantes JOIN anunciante_invertido AS a_i0 ON anunciantes.id = a_i0.id_anunciante JOIN indice_invertido AS indice0 ON a_i0.id_invertido = indice0.id LEFT OUTER JOIN domicilios ON anunciantes.id = domicilios.id_anunciante LEFT OUTER JOIN localidades ON domicilios.id_localidad = localidades.id LEFT OUTER JOIN provincias ON provincias.id = localidades.id_provincia WHERE anunciantes.estado = 1 AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') GROUP BY provincias.id ORDER BY cantidad DESC And this is the query explained (hope it can be read in this format): id select_type table type possible_keys key key_len ref rows Extra 1 PRIMARY anunciantes ref PRIMARY,estado estado 1 const 36669 Using index; Using temporary; Using filesort 1 PRIMARY domicilios ref id_anunciante id_anunciante 4 db84771_viaempresas.anunciantes.id 1 1 PRIMARY localidades eq_ref PRIMARY PRIMARY 4 db84771_viaempresas.domicilios.id_localidad 1 1 PRIMARY provincias eq_ref PRIMARY PRIMARY 4 db84771_viaempresas.localidades.id_provincia 1 1 PRIMARY a_i0 ref PRIMARY,id_anunciante,id_invertido PRIMARY 4 db84771_viaempresas.anunciantes.id 1 Using where; Using index 1 PRIMARY indice0 eq_ref PRIMARY PRIMARY 4 db84771_viaempresas.a_i0.id_invertido 1 Using index 6 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 6 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index 5 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 5 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index 4 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 4 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index 3 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 3 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index 2 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 2 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index
