  • Need a tool to search large structure text documents for words, phrases and related phrases

    - by pitosalas
    I have to keep up with structured documents containing things such as requests for proposals, government program reports, threat models and all kinds of things like that. They are in techno-legalese as I would call them: highly structured, with section numbering and 3, 4 and 5 levels of nesting. All in English I need a more efficient way to locate those paragraphs of nuggets that matter to me. So what I’d like is kind of a local document index/repository, that would allow me to have some standing queries and easily locate sections in documents that talk about my queries. Here’s an example: I’d like to load in 10 large PDF files, each of say 100 pages. Each PDF contains English text, formatted very nicely into paragraphs and sections. I’d like to specify that I am interested in “blogging platforms”, “weaknesses in Ruby”, “localization and internationalization” Ideally then look at a list that showed the section of text, the name of the document, and other information that seemed to be related to and/or include the words and phrases I specified. I am sure something like this exists. I would call it something like document indexing, document comprehension or structured searching.

  • MySQL - optimising selection across two linked tables

    - by user293594
    I have two MySQL tables, states and trans: states (200,000 entries) looks like: id (INT) - also the primary key energy (DOUBLE) [other stuff] trans (14,000,000 entries) looks like: i (INT) - a foreign key referencing states.id j (INT) - a foreign key referencing states.id A (DOUBLE) I'd like to search for all entries in trans with trans.A 30. (say), and then return the energy entries from the (unique) states referenced by each matching entry. So I do it with two intermediate tables: CREATE TABLE ij SELECT i,j FROM trans WHERE A30.; CREATE TABLE temp SELECT DISTINCT i FROM ij UNION SELECT DISTINCT j FROM ij; SELECT energy from states,temp WHERE id=temp.i; This seems to work, but is there any way to do it without the intermediate tables? When I tried to create the temp table with a single command straight from trans: CREATE TABLE temp SELECT DISTINCT i FROM trans WHERE A30. UNION SELECT DISTINCT j FROM trans WHERE A30.; it took a longer (presumably because it had to search the large trans table twice. I'm new to MySQL and I can't seem to find an equivalent problem and answer out there on the interwebs. Many thanks, Christian

  • MySQL FULLTEXT aggravation

    - by southof40
    Hi - I'm having problems with case-sensitivity in MySQL FULLTEXT searches. I've just followed the FULLTEXT example in the MySQL doco at http://dev.mysql.com/doc/refman/5.1/en/fulltext-boolean.html . I'll post it here for ease of reference ... CREATE TABLE articles ( id INT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY, title VARCHAR(200), body TEXT, FULLTEXT (title,body) ); INSERT INTO articles (title,body) VALUES ('MySQL Tutorial','DBMS stands for DataBase ...'), ('How To Use MySQL Well','After you went through a ...'), ('Optimizing MySQL','In this tutorial we will show ...'), ('1001 MySQL Tricks','1. Never run mysqld as root. 2. ...'), ('MySQL vs. YourSQL','In the following database comparison ...'), ('MySQL Security','When configured properly, MySQL ...'); SELECT * FROM articles WHERE MATCH (title,body) AGAINST ('database' IN NATURAL LANGUAGE MODE); ... my problem is that the example shows that SELECT returning the first and fifth rows ('..DataBase..' and '..database..') but I only get one row ('database') ! The example doesn't demonstrate what collation the table in the example had but I have ended up with latin1_general_cs on the title and body columns of my example table. My version of MySQL is 5.1.39-log and the connection collation is utf8_unicode_ci . I'd be really grateful is someone could suggest why my experience differs from the example in the manual ! Be grateful for any advice.

  • I'm trying to build a query to search against a fulltext index in mysql

    - by Rockinelle
    The table's schema is pretty simple. I have a child table that stores a customer's information like address and phone number. The columns are user_id, fieldname, fieldvalue and fieldname. So each row will hold one item like phone number, address or email. This is to allow an unlimited number of each type of information for each customer. The people on the phones need to look up these customers quickly as they call into our call center. I have experimented with using LIKE% and I'm working with a FULLTEXT index now. My queries work, but I want to make them more useful because if someone searches for a telephone area code like 805 that will bring up many people, and then they add the name Bill to narrow it down, '805 Bill'. It will show EVERY customer that has 805 OR Bill. I want it to do AND searches across multiple rows within each customer. Currently I'm using the query below to grab the user_ids and later I do another query to fetch all the details for each user to build their complete record. SELECT DISTINCT `user_id` FROM `user_details` WHERE MATCH (`fieldvalue`) AGAINST ('805 Bill') Again, I want to do the above query against groups of rows that belong to a single user, but those users have to match the search keywords. What should I do?

  • android imageview scrolling to display full high quality image

    - by Javadid
    hi friends... i am working on displaying an image and placing an icon on top of it... clicking the icon will show an enlarged version of the image... though putting the imageview holding the image in a LinearLayout scales the image to the width of the dialog, the problem is that i need to display the image in a dialog but the image is very high resolution and hence is far bigger than the width of the dialog... I need to show the actual image with scrolling for both ways to see the whole image... But whenever i try putting the imageView in a scrollview the top of my imageview is blank... and again though image scrolls downwards the width is scaled to the width of the dialog... Helppppppppp guys....

  • RewriteCond and Full QUERY_STRING

    - by Tim
    I'm having hard time getting my head wrapped around this one - and it should be trivial. I would like to redirect one URL with a specific query string to another URL. I want to send any requests that contain the query string in the URL http://mysite.com/index.php?option=com_user&view=register To: http://mysite.com/index.php?option=com_regme&view=form&regme=4&random=0&Itemid=6 If they add anything to the end of the first URL, it should still go to the second URL so that they cannot bypass the redirection. Nothing in the first query string needs to be preserved and passed to the second - all I want to do is change the URL completely. I'm tearing my hair out trying to get this to work yet it should be trivial. Suggestions? Thanks, -Tim

  • Inner join on 2 arrays?

    - by russ
    I'm trying to find a solution to the following (I'm thinking with Linq) to the following: I need to pull down certain files from a larger list of files on an ftp server that have a similar file name. For example, we send an order file to some company for processing then they return a response file that we can download. So, I could send them the files "order_123.txt" and "order_456.txt". After a certain amount of time I need to go look for and download the responses for those files that will be named "order_123.resp" and "order_456.resp". The kicker is that in some cases I can have multiple responses in which case they would create "order_123-1.resp" and "order_123-2.resp" and also the files don't get removed from the server. I know this can be accomplished by looping through the files I know I need responses to then loop through all the files on the server until I find files that match but I'm hoping that I don't have to loop through the files on the server more than once. This example may help clarify: I've sent "order_222.txt" and "order_333.txt" they processed them and the ftp server contains: "order_111-1.resp" "order_001.resp" "order_222-1.resp" "order_222-2.resp" "order_333.resp" I need to download the 3rd, 4th, and 5th file. Thanks.

  • .Net Entity Framework & POCO ... querying full table problem

    - by Chris Klepeis
    I'm attempting to implement a repository pattern with my poco objects auto generated from my edmx. In my repository class, I have: IObjectSet<E> _objectSet; private IObjectSet<E> objectSet { get { if (_objectSet == null) { _objectSet = this._context.CreateObjectSet<E>(); } return _objectSet; } } public IQueryable<E> GetQuery(Func<E, bool> where) { return objectSet.Where(where).AsQueryable<E>(); } public IList<E> SelectAll(Func<E, bool> where) { return GetQuery(where).ToList(); } Where E is the one of my POCO classes. When I trace the database and run this: IList<Contact> c = contactRepository.SelectAll(r => r.emailAddress == "[email protected]"); It shows up in the sql trace as a select for everything in my Contact table. Where am I going wrong here? Is there a better way to do this? Does an objectset not lazy load... so it omitted the where clause? This is the article I read which said to use objectSet's... since with POCO, I do not have EntityObject's to pass into "E" http://devtalk.dk/CommentView,guid,b5d9cad2-e155-423b-b66f-7ec287c5cb06.aspx

  • Algorithm for multiple word matching in a text, count the number of every matched word

    - by 66
    I have noticed that it has solutions for matching multiple words in a given text, such as below: http://stackoverflow.com/questions/1099985/algorithm-for-multiple-word-matching-in-text If I want to know exactly the number of appearances of each matched word in the text, my solution is like this: step 1: using ac-algorithm to obtain the maching words; step 2: count the number of each word obtained in step 1 is there a faster way? Thx~

  • MS SQL: Primary file group is full

    - by aximili
    I have a very large table in my database and I am starting to get this error Could not allocate a new page for database 'mydatabase' because of insufficient disk space in filegroup 'PRIMARY'. Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. How do you fix this error? I don't understand the suggestions there.

  • Effective Method to Manage and Search Through 100,000+ Objects Instantly? (C#)

    - by Kirk
    I'm writing a media player for enthusiasts with large collections (over 100,000 tracks) and one of my main goals is speed in search. I would like to allow the user to perform a Google-esque search of their entire music collection based on these factors: Song Path and File Name Items in ID3 Tag (Title, Artist, Album, etc.) Lyrics What is the best way for me to store this data and search through it? Currently I am storing each track in an object and iterating over an array of these objects checking each of their variables for string matches based on given search text. I've run into problems though where my search is not effective because it is always a phrase search and I'm not sure how to make it more fuzzy. Would an internal DB like SQLlite be faster than this? Any ideas on how I should structure this system? I also need playlist persistence, so that when they close the app and open the app their same playlist loads immediately. How should I store the playlist information so it can load quickly when the application starts? Currently I am JSON encoding the entire playlist, storing it in a text file, and reading it into the ListView at runtime, but it is getting sluggish over 20,000 tracks. Thanks!

  • MYSQL - SELECT ALL FROM TABLE if...

    - by hornetbzz
    Hello I have a (nice) mysql table built like this : Fields Datas id (pk) 1 2 3 4 5 6 master_id 1000 1000 1000 2000 2000 2000 ... master_name home home home shop shop shop ... type_data value common client value common client ... param_a foo_a 1 0 bar_a 0 1 ... param_b foo_b 1 0 bar_b 1 0 ... param_c foo_c 0 1 bar_c 0 1 ... ... ... ... ... ... ... ... ... All these datas are embed in a single table. Each datas are dispatched on 3 "columns" set (1 for the values, 1 for identifying if these are common values and one for identifying client values). It's not the best I got but many other scripts depends on this structure. I'd need sthg like this: SELECT parameters name (eg param_a, param_b..) and their values (eg foo_a, foo_b..) WHEN master_id=? AND type_data=(common or client) (eg for values=1 on the 2nd column) . in order to get the parameters hash like param_a => foo_a param_b => foo_b param_c => foo_c ... I could not succeed in self joining on the same table till now but I guess it should be feasible. (I'd like to avoid to do several queries) Thx in advance

  • Mysql advanced SELECT, or multiple SELECTS? Movies keywords

    - by Supyxy
    I have a mysql database with movies as follows: MOVIES(id,title) KEYWORDS_TABLE(id,key_id) [id is referenced to movies.id, key_id is refernced to keywords.id] KEYWORDS(id,keyword) //this doesn't matter on my example.. Basically i have movies with their titles and plot keywords for each one, i want to select all movies that have the same keywords with with a given movie id. I tried something like: SELECT key_id FROM keywords_table WHERE id=9 doing that in php and storing all the IDs in an array $key_id.. then i build another select that looks like: SELECT movies.title FROM movies,keywords_table WHERE keywords_table.key_id=$key_id[1] OR keywords_table.key_id=$key_id[2] OR ......... OR keywords_table.key_id=$key_id[n] This kinda works but it takes too much time as we talk about a database with thousands of thousands of records. So, any suggestions?? thanks!

  • Rails advanced queries with join and sum calculation

    - by Dustin Brewer
    I have two models: companies and expenses. Companies have many expenses and expenses belong to companies. My expense model has an 'amount' column. I was wondering if there is a way to perform a find based on a date range and the amount column of the expenses. Something like top 3 companies by total expense amounts over a 7 day period. I've tried for the better part of the day to get this to work, I've attempted joins, chaining named scopes, raw sql, etc. and I'm not having any luck. Thanks for the help.

  • How well does Solr scale over large number of facet values?

    - by Continuation
    I'm using Solr and I want to facet over a field "group". Since "group" is created by users, potentially there can be a huge number of values for "group". Would Solr be able to handle a use case like this? Or is Solr not really appropriate for facet fields with a large number of values? I understand that I can set facet.limit to restrict the number of values returned for a facet field. Would this help in my case? Say there are 100,000 matching values for "group" in a search, if I set facet.limit to 50. would that speed up the query, or would the query still be slow because Solr still needs to process and sort through all the facet values and return the top 50 ones? Any tips on how to tune Solr for large number of facet values? Thanks.

  • How to index a string like "aaa.bbb.ddd-fff" in Lucene?

    - by user46703
    Hi, I have to index a lot documents that contain reference numbers like "aaa.bbb.ddd-fff". The structure can change but it's always some arbitrary numbers or characters combined with "/","-","_" or some other delimiter. The users want to be able to search for any of the substrings like "aaa" or "ddd" and also for combinations like "aaa.bbb" or "ddd-fff". The best I have been able to come up with is to create my own token filter modeled after the synonym filter in "Lucene in action" which spits out multiple terms for each input. In my case I return "aaa.bbb", "bbb.ddd","bbb.ddd-fff" and all other combinations of the substrings. This works pretty well but when I index large documents (100MB) that contain lots of such strings I tend to get out of memory exceptions because my filter returns multiple terms for each input string. Is there a better way to index these strings?

  • Two Applications using the same index file with Hibernate Search

    - by Dominik Obermaier
    Hi, I want to know if it is possible to use the same index file for an entity in two applications. Let me be more specific: We have an online Application with a frondend for the users and an application for the backend tasks (= administrator interface). Both are running on the same JBOSS AS. Both Applications are using the same database, so they are using the same entities. Of course the package names are not the same in both applications for the entities. So this is our usecase: A user should be able to search via the frondend. The user is only allowed to see results which are tagged with "visible". This tagging happens in our admin interface, so the index for the frontend should be updated every time an entity is tagged as "visible" in the backend. Of course both applications do have the same index root folder. In my index folder there are 2 index files: de.x.x.admin.model.Product de.x.x.frondend.model.Product How to "merge" this via Hibernate Search Configuration? I just did not get it via the documentation... Thanks for any help!

  • sql server: import operation won't copy full schema

    - by P a u l
    I recall that the import tool in sql server 2000 would copy indexes, relationships, etc. In sql server 2005/2008 the import tool in SSMS will only create the tables, copy the data, but the keys, indexes, relationships are missing. I can find no option in the import wizard to enable this? What am I missing here? Is this not possible anymore for any good reason?

  • Simplifying and reducing the cost of an anti-join query

    Hi, Could you please help me in simplifying and reducing the cost of the below query? I tried making it a co-related subquery with NOT EXISTS but it didn't give me any output. Please note that the table in both main and inner query is the same 'table_1". SELECT * FROM Table_1 A WHERE A.Col1 = 'abcd' AND (A.Col2, A.Col3) NOT IN (SELECT Col2, Col3 FROM Table_1 B WHERE (B.Col4 IN (1,2,3) And B.Col5 In ('x','y')) OR (B.Col4 = 1 AND B.Col5 = 'z' AND B.Col6 = 'f') )) Thanks in advance, Savitha
