Hello,
I have a table with a FULLTEXT index on a column of type 'text'. Searches on this table using MATCH() AGAINST() work fine for most words. However, I needed to match against a 3 letter word. So I lowered the ft_min_word_len to 3 in /etc/my.cnf. I then restarted MySQL. I checked that the variable was set to 3 in the running mysqld.
I don't see that you rebuilt your FULLTEXT indexes after restarting the server. Did you?
But for some reason, I cannot fetch any results:
mysql> select title_id from support_doc_articles where match(article) against ('dns'); Empty set (0.00 sec)
It does not work IN BOOLEAN MODE either:
mysql> select title_id from support_doc_articles where match(article) against ('dns' IN BOOLEAN MODE); Empty set (0.00 sec)
Actually, I just tried it again, searching for the 3 letter word 'key', and it brought back results. Is 'dns' in the stopwords list? Is there any way I can see what words are in there? Can I exclude words from the stopword list without recompiling MySQL?
They're in the file myisam/ft_static.c in the source distribution. dns is not one of them.
I don't believe you can exclude words from the list without recompiling.
Thanks for any help. -- Justin Hopper UNIX Systems Engineer Spry Hosting http://www.spry.com
