FullText index performance issue

Hi, I'm running a fulltext query on a ~50000 record mysql database and
while performance is usually satisfying - about 0.02 secs per query, i
get a critical performance deterioration when looking for popular
keywords (words that appear in more than 50% of the data) - about 0.25
secs/query. I know that the standard fulltext engine does not return
any results on such words, and this is good, but this does not explain
the performance issue. Any ideas?

Relevancy scores are normally defined by a MySQL query on a table that has a fulltext index. The rules for relevancy scoring will exclude certain words due to their being too short (minimum default is 4 letters). This is the Fed. Everything is a TLA (three-letter acronym). Therefore, since I'm building a PORTABLE web application, changing MySQL's default settings for fulltext index querying is completely undoable and unrealistic, so...

Hi all, I'm planning to use MySQL's full-text search for my forum system (possibly 5+ million posts). I've been playing with it a lot lately to see the performance and functionality and have some suggestions/questions. First, since a few of you may be wanting to know, here is a thread where I was doing some speed/optimization tests and stuff with 3 million posts: http://www.sitepointforums.com/showthread.php?threadid=69555

Retracing my problem leads me to believe I never successfully created fulltext indexes for MySQL 3.23.58 MyISAM tables. I went to the MySQL manual and was able - or so I thought - to create them, however, my fulltext search queries fail in 3.23.58 but the exact queries (with same data) work perfectly in 4.0.10. --...

I accept that fulltext index would be bloated due to all the atomic indexing it has to do. BUT, looking at my mysql db directory, for each table, there is a single index file consisting of all the indecis - regular and fulltext put together. The result is that to access any simple index, the whole monsterous index file has to be pulled into ram, sucking life out of my server.

I have a large contacts table with about 30 columns of text fields and 5 fulltext indexes spanning the different sections of the table. I'm curious if anyone could suggest a better way to find rows in the table based on text entered by the user. It also would be nice if wildcards could be supported like "beginning*". The query I have built crashed mysqlnt-d a few times but I was unable to determine what triggered the crash. I believe it...

I read a while back that MySQL will only use one index per query. (If this is not so, please tell me and point me to a doc that gives a good explanation of MySQL's current index usage policy).

(originally posted in database.myodbc by mistake) I'm trying to speed up a fulltext search (MySQL 5.0.21, table has 670,000 records, about 900MBytes, machine has 1GB memory). Fulltext search speed is quite variable -- sometimes really fast, sometimes quite slow, so I'm trying to identify ways to make it more consistent.

Hi all, Maybe this belongs in the Full Text group but I am writing an ASP.NET application with a SQL Server 2005 backend, so I am posing the question here. I have been using fulltext search on a text field for a while because originally the field was only being updated nightly and I could repopulate/rebuild the index nightly. Now I will be allowing users to Update the field in real-time. I am using a simple Update SQL statement to...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
