I wuld like to do som automatic tagging of incoming text in our system and I was wondering if a full-text index is capable of providing a a ranked list of words given an indexed row. If not, do you have any suggestions on how to do this? We already have a system in place for auto tagging but its fairly brute-force (aka. slow) in its met...
I have a table Books in my MySQL database which has the columns Title (varchar(255)) and Edition (varchar(20)). Example values for these are "Introduction to Microeconomics" and "4". I want to let users search for Books based on Title and Edition. So, for example they could enter "Microeconomics 4" and it would get the proper result. My...

I am a bit lost, this looks like some silly mistake - but I have no clue what that can be. Here is the test session: mysql> drop table articles; Query OK, 0 rows affected (0.02 sec) mysql> CREATE TABLE articles (body TEXT, title VARCHAR(250), id INT NOT NULL auto_increment, PRIMARY KEY(id)) ENGINE = MYISAM; Query OK, 0 rows affected (...
Hi, the project I'm working on has for each column that needs to be searched a second column called "ft[columnname]" which has a FULLTEXT index and only this one is searched against. This column contains an "optimized" text, that is automatically generated from the original column in the following way: The string is lowercased All acc...
I'm using FULLTEXT natural language search, and I notice that it automatically sorts my results by relevance. However, when I start to add things to ORDER, it seems to no longer sort by relevance. Is there a way to explicitly set the importance of relevance sorting? ...

Im using fulltext for searches on my site, but there are a lot of updates being done to the table also, which contains 700,000 records. these updates are usually done via cron, by a script that runs every 10 minutes and commits changes from a temporary table where I simply INSERT all the changes for speed purposes, since updating the liv...
We have a system that is migrating from an older VARCHAR using LIKE setup to one that uses FULLTEXT indexes. So far everyone is enjoying the switch, but we still have some code that isn't catered to the FULLTEXT queries. Currently we have a column that is a VARCHAR(255) and we want to remove the 255 character limit. What will happen to ...
So far, I'm not getting meaningful results from my full-text queries so I decided to give a simple example of what I am trying to do and the results I expect. I've made the the following test table (tblCars) with full-text enabled for the column [Car] and primary key [CarID]. CarID Car ----- ----------------- 9 BMW 330Ci 2009 14 ...

Let's say I've got two tables: NOTES has two columns: ID and BODY. BODY is a FULLTEXT index. KEYWORDS has two columns: ID and KEYWORD. I want to search every BODY for every KEYWORD and get one row for each match, the NOTES.ID and the KEYWORD.ID. So if there were 15 notes and each one matched 3 keywords, I would get 45 rows. But as ...

However when using this SQL ("skitt" is used as a search term just so I can try match Skittles). SELECT id,name,description,price,image, MATCH...
Is there a way to use FULLTEXT in a multi-language table without giving each language its own column? I have one column I need to search, but the language in that column varies: ProductID int Description nvarchar(max) Language char(2) Language can be one of: en, de, it, kr, th Currently I build a concordance and use that for...
I'd like to perform a fulltext search against a column, looking for a partial word match (IE: against('fra*' in boolean mode)). But I would like to receive results that assign a higher relevancy to shorter words that match. So, for example, if I perform a search for 'fra' and get the results 'frank', 'fran' and 'frankfurter', I would ...
I have created a fulltext catalog that stores the data from some of the columns in a table, but the contents seem to have been split apart by characters that I don't really want to be considered word delimiters. ("/", "-", "_" etc..) I know that I can set the language for word breaker, and http://msdn.microsoft.com/en-us/library/ms34518...
