OSQA use MySQL fulltext search clause "MATCH (colum) AGAINST( 'word' IN BOOLEAN MODE)" in forum_mysqlftsindex. for that to work the table forum_node have to have a have an trigger. For setup there is an sql script in forum_modules/mysqlfulltext. The search will lock for the word in title, body or tags.

But sometime this search will no find the word there. I do not know why.
