Hi,
I've just started to implement a FULLTEXT search script in PHP. I have
read that the relevance rating should not directly be used to create a
rating (as a percentage say) for the results you may return to a user.
Is there an effective algorithm whereby some normalisation etc. could
effectively be used to provide at least a "rough" guide?

How do I change a MYSQL Fulltext relevance value to: 0 to 100%. I'm just
thinking about usability for the "average" user - maybe they would like
to know...and would not understand the raw value.
Any snips, ideas or links appreciated.
Thanks

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

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 have a very large table with book titles. How can I use Mysql to do a
fulltext search that returns rows that only contains the words that the
user searched for, ordered by relevance? Note, rows that contains some
of the words, but not all - should NOT be in the result.
My database contains >5 000 000 rows. So speed is an issue. The index
itself may be very large if needed.
What's the best way to achive this with MySQL?

Given the SQL shouldn't the records be sorting by score ie. relevance? I
thought if "WHERE MATCH" is used it will sort that way. Thanks
mysql> SELECT `page`.`title` , MATCH ( `title` , `descrip` ) AGAINST (
'+code+nasdac' IN BOOLEAN MODE ) AS SCORE FROM `page` WHERE MATCH (
`title` , `descrip` ) AGAINST ( '+code+nasdac' IN BOOLEAN MODE );

Show full header Is there any way to make relevance when using boolean
mode more useful? If not, are there plans in the Fulltext development
"todo" for making it useful?
I'm thinking of just counting the keyword occurences in records with a
PHP script somehow and using that to order the records somehow. Or doing
a non boolean fulltext search w/relevance first and then melding that in
somehow with a boolean search.
See my results...

The idea of this is very simle. The site is 800px wide and sits in the
middle of the browser window, on either side of the site I want a different
background image aligned against it. If I were doing this with table based
layout the code would be as follows:
<head>
<style type="text/css">
#bgleft {
background: url(left_half_circle.gif) right top repeat-y;

Hi,
I am just trying to develop a search system for my website. The PHP side of things is no trouble at all. I have also set up what I think are appropriate FULLTEXT indices on the tables I will need to search.
I was just trying things out and have got a bit confused. What I think should be happening, based on what I've read, is not happening.
I have a table - tbl_resource, on this table there is FULLTEXT index on three fields -...

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...
