• search engine (solr/sphinx) question

  - by noname

  i want to make my threads content searchable with full text search engines like solr. but i wonder one thing. should i index just the thread.title, thread.body and post.body or should i index username, created date, nr of posts, views, country, region and city too that belongs to thread? i mean when an user search for a thread he will get hits returned containing thread title, 2 lines of body, which user has posted it, creation date, tags, and so on. should i index all this information too? but then it would be pretty much the whole database. or should i just index the 3 first columns i mentioned for full text search. and another question. when an user post a new thread, then i have to immidiately tell solr to add that row? if im not, how would it be searchable?

• Adding a search box to a windows forms web browser control that highlights text

  - by evan

  I have a windows forms (using c#) application. It displays a webpage and has a textbox/botton combination which can be used to search for text displayed to the user. Currently I search the inner text of all elements for the text in the textbox. And then I weed out the elements that are redundant (for example a word could be in a 'p' and 'b' element where the 'b' is a child element of 'p' so the element returned should be 'b'). Finally I run the ScrollIntoView(true) method on the found element. I'd now like to add a function that highlights the text (like if you search for a term in a real webbrowser). My first thought was to just inject html and or javascript code around the text but that seems like a messy solution. Any ideas on how I should do this? Thanks for your help!

• What's the best way to tell if a file exists in a directory?

  - by Nano HE

• Facebook profile search using email address of a user

  - by agdev

  Hello, If I have email address of a user, is there any way to find the profile of the user? I know it can be done using the uid and name of the user (GetInfo() or fql.query). The specific problem I am trying to address is when I search for a user using the name field, I end up getting multiple results (people with the same name). I have the email address of the user I want to search, so if I can search using email address, I will be able to reach to the specific user. Alternately, if there's a way to find uid for a given email address, I can get the user I am looking for. Any help is much appreciated. Thanks!

• Search Result displaying-like google php

  - by Ramesh

  i have an paragraph and user will search inside that and if the search term has 3 matches inside but all are in 3 different places ex World War II, or the Second World War[1] (often abbreviated WWII or WW2), was a global military conflict lasting from 1939 to 1945 which involved most of the world's nations, including all of the great powers, organised into two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, with more than 100 million military personnel mobilised. In a state of "total war," the major participants placed their entire economic, industrial, and scientific capabilities at the service of the war effort, erasing the distinction between civilian and military resources. Marked by significant action against civilians, including the Holocaust and the only use of nuclear weapons in warfare, it was the deadliest conflict in human history,[2] with over seventy million casualties. i have to search "war" so that it should display like World War II, or the Second World War[1].....In a state of "totalwar,".... some thing like this ///

• Accented character replacement for search then reinserted afterwards

  - by user314573

  Basically my issue is that users would like to search for a french word that has accented characters but without typing in the accented characters and then have the actual accented word appeared highlighted if found... So for example they would type in "declare" but in the result sets it would look like "déclare" and if found "déclare" would be highlighted. My first thought was to just simply replace the characters with a regex but then I remembered that I would need to re-insert the replaced characters after the search... I was thinking of then using some sort of character map that would track position and the character so that when the search was finshed I could put the result set back to the way it was. This seems a little brute force to me and I was wondering if anyone had a better alternative? I'm using Visual Studio 2005 with this app. Any advice would be much appreciated! Thanks

• PHP regex to search across multiple lines

  - by Gaz

  I'm using preg_* in PHP to search for the pattern <!-- %{data=THIS GETS MATCHED}% --> and pull out the matched text. The pattern for this is: preg_match('#<!-- %{' . $knownString . '\s*=\s*(.*?)}% -->#', ...) What I would like it to do is search across multiple lines for the string. For example: <!-- %{data= THIS GETS MATCHED AND RETURNED }% --> How can I edit my current pattern to have this search ability?

• Twitter search c#

  - by Lily

  Hi, I have implemented a method which manually scrapes the Search Twitter page and gets the tweets on different pages. But since there is a fast refresh rate, the method triggers an exception. Therefore I have decided to use TweetSharp API instead var search = FluentTwitter.CreateRequest() .AuthenticateAs(TWITTER_USERNAME, TWITTER_PASSWORD) .Users().SearchFor("dumbledore"); var result = search.Request(); var users = result.AsUsers(); this code was on the site. Does anyone know how I can avoid giving my credentials and retrieve from all users and not just the ones I have as friends? Thanks!

• How to test Text Search accuracy and efficiency?

  - by DEN

  I have created a web application. One of the feature is text search which perform the boolean operator ( NOT, AND, OR) as well. However, I have no idea on calculating the search's accuracy and efficiency. For example: 1 . Probe identification system for a measurement instrument 2 . Pulse-based impedance measurement instrument 3 . Millimeter with filtered measurement mode when the user key in will return the result as below input :measurement instrument Result: 1,2 input : measurement OR instrument NOT milimeter Result: 1,2,3 so, i have no idea on what issue and what algorithm to calculate on the accuracy and efficiency of the text search.. anyone have any idea on that?

• Outlook Macro to Search

  - by Corpa Loom

  What's the best way to automate this function? I want to be able to do this in Outlook 2010, (1)select a specific mail account (2)Key in a folder that I am looking for (3)Then have the macro/program fire off an "*" asterisk (4)Then insert the text that I keyed in step one. I am trying to automate the search for a folder hot-keys that already exist. My problem is that I can't type the folder that I am looking for fast enough and all the search programs that I have used are far too slow. The hot-key search is awesome and super fast, I just can't type the folder that I am looking for fast enough. Can this process be automated? And I can't use this code, it is far too slow: http://www.vboffice.net/sample.html?mnu=2&smp=82&cmd=showitem&lang=en

• Is using .h as a header for a c++ file wrong?

  - by Chris Huang-Leaver

  Is using .h as a header for a c++ file wrong? I see it all over the place, especially with code written in the "C style". I noticed that Emacs always selects C highlighting style for a .h header, but c++ for hpp or hh. Is it actually "wrong" to label your headers .h or is it just something which annoys me? EDIT: There is a good (ish) reason why this annoys me, if I have project files labelled, 'hpp & cpp' I can get away with 'grep something *pp' etc. otherwise I have to type '.h cpp'

• Optimality of Binary Search

  - by templatetypedef

  Hello all- This may be a silly question, but does anyone know of a proof that binary search is asymptotically optimal? That is, if we are given a sorted list of elements where the only permitted operation on those objects is a comparison, how do you prove that the search can't be done in o(lg n)? (That's little-o of lg n, by the way.) Note that I'm restricting this to elements where the only operation permitted operation is a comparison, since there are well-known algorithms that can beat O(lg n) on expectation if you're allowed to do more complex operations on the data (see, for example, interpolation search). Thanks so much! This has really been bugging me since it seems like it should be simple but has managed to resist all my best efforts. :-)

• jQuery Photo Search Results Pagination using AJAX and JSON

  - by Mark Richman

  I have a "photo search" page that needs to present search results in a 5x5 grid of photo thumbnails. I'd like to populate this grid using the JSON results of a jQuery $.ajax() call to my ASP.NET web service. Where I'm struggling is with pagination, where clicking [First][Prev][1][2][3]...[20][21][Next][Last] will call back again via ajax and repopulate the results with the appropriate images. So I need to find a solution to both the pagination control itself and the search results. Is there a jQuery plugin for this, or something I can easily adapt for my purposes?

• Calling Google's Custom Search API via Python

  - by user353829

  I am writing in Python a module that will query Google's Custom Search API and return all listings of domain 'example.com' I Have been reading instructions at https://code.google.com/apis/customsearch/v1/getting_started.html and am a little stumped at the moment. Are my assumptions listed below correct? For example, to search for results that has 'example.com' in the URL, the query is: *'https://www.googleapis.com/customsearch/v1?key=my_key&cx=017576662512468239146:omuauf_lfve&q=site:example.com*' *key=my_key*: value of key given by google cx=017576662512468239146: name of the search engine (google)? *omuauf_lfve*: I have no idea what this is q=site:example.com: This should return all results with 'example.com'; e.g. www.a.example.com, b.example.com, example .com

• Launching and Intent from file and mime type

  - by stonedonkey

  I've reviewed all the similar questions here, but I can't for the life of me figure out what I'm doing wrong. I've written an application that tries to launch various files, sort of a file browser, when a file is clicked it tries to launch the program based on it's associated MIME type or I want it to present the "Choose Application to Launch" dialog. Here's the code I'm using to launch: File file = new File(app.mediaPath() + "/" +_mediaFiles.get(position)); Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW); String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(file).toString()); String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension); myIntent.setDataAndType(Uri.fromFile(file),mimetype); startActivity(myIntent); This fails and generates a: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=file:///file:/mnt/sdcard/roms/nes/Baseball_simulator.nes } Now if I install OI File Manager for instance, it opens instead of this error being thrown, and then if I click the same file from within in it, it launches the approriate dialogs. I have noticed that the MIME type for that particular file fails, but other mime types like .zip do return values. Am I missing something that when the MIME type is null to call a dialog that lets the user select? I've tried other variations of launching the app, including not setting the mime type and only using .setData with no success. The action I want to happen is, a user clicks a file, if it's associated with an application that app launches, if not, the user gets the "Complete action using" dialog with a list of apps. Thanks for any advice.

• Good way to send a large file over a network in C#?

  - by BFreeman

  I am trying to build an application that can request files from a service running on another machine in the network. These files can be fairly large (500mb + at times). I was looking into sending it via TCP but I'm worried that it may require that the entire file be stored in memory. There will probably only be one client. Copying to a shared directory isn't acceptable either. The only communication required is for the client to say "gimme xyz" and the server to send it (and whatever it takes to ensure this happens correctly). Any suggestions?

• Problem when exiting search in iPhone

  - by camilo

  Hi. I have a search display controller, and it is searching well. I'm searching in a table with several sections and I have a viewForHeaderInSection function working as it's supposed to. When I start searching, my numberOfSectionsForTableView returns 1, and I have a special view saying "Search Results" wich I use in self.searchDisplayController.searchResultsTableView. The problem happens when I select a row in my searchResultsTableView: I change the view, and when I return and try to exit the searchDisplayController (by pressing the CancelButton), the tables change nice, but changing the viewforHeader for my first section is not "pretty". I have a "kind-of-click" anymation. I would like it to not be so noticeable for the user, having a more "fluid" change. Anybody had the same problem and knows how to solve it? In a different question (which would work as a workaround): how can I hide the keyboard while searching without pressing the Cancel or Search buttons? Thanks a lot!

• database search function on an HTML page possible?

  - by synergy989

  Not sure if this is against stackoverflow rules as it's not a specific code question but I really need a little help. I want to know if it is possible to create a search feature (search box) on an HTML webpage that will query a database and return the results? Basically I have a database of products and their related categories. A user would come to the website, enter the category in the search field...somehow query the database and return the results on a new page. Note: the results page doesn't have to be HTML (could be PHP etc). If you could also include a little guidance on how (please nothing detailed, just need a direction). Thank you!

• Lucene case sensitive & insensitive search

  - by zvikico

  I have a Lucene index which is currently case sensitive. I want to add the option of having a case insensitive search as a fall-back. This means that results that match the case will get more weight and will appear first. For example, if the number of results is limited to 10, and there are 10 matches which match my case, this is enough. If I only found 7 results, I can add 3 more results from the case-insensitive search. My case is actually more complex, since I have items with different weights. Ideally, having a match with "wrong" case will add some weight. Needless to say, I do not want duplicate results. One possible approach is to have 2 indexes. One with case and one without and search both. Naturally, there's some redundancy here, since I need to index twice. Is there a better solution? Ideas?
