Re: Full-Text problems
Perhaps the searches that return nothing are actually matching more than 50% of the record in the table. From the manual: In addition, words that are present in more than 50% of the rows are considered common and do not match. - Original Message - From: Taco Fleur [EMAIL PROTECTED] To: mysql@lists.mysql.com Sent: Wednesday, June 21, 2006 12:21 AM Subject: Full-Text problems Hi all, I am experiencing some issues with Full-Text and was hoping someone could shed some light on the following. I have some content which I know contains for example the word news, the table is MyISAM, the column type is LONGTEXT, there is an index on the column of FULLTEXT. I have adjusted the system variables so that the minimum word length is 2 (ft_min_word_len = 2) and the stop word file is set to (ft_stopword_file = '') Can anyone tell me why it is not picking up the word news plus some others? I have verified that the system picked up the new variable settings with SHOW VARIABLES I have also deleted everything in that table and reinserted the content, which I hope rebuilds the table? Other words that do not appear are; - dealer - sign in - contact I have verified that it returns other results, i.e. when searching on words like; - headline - engineering - user - her The query is as below SELECTI.indexIdentity , I.webpageIdentity , I.content , I.indexDate , MATCH ( I.content ) AGAINST ( '#form.searchString#' ) AS score , W.universalResourceLocator , W.title FROMtbl_index I INNER JOIN tbl_webpage W ON I.webpageIdentity = W.webpageIdentity WHEREMATCH ( I.content ) AGAINST ( '#form.searchString#' ) ORDER BY score DESC; The content is text I gathered from our webpages, I am basically trying to create a site search.

RE: Full-Text problems
Is there any way to test this? I doubt it is 50%, some of these words only appear once or twice within the content.

Re: Full-Text problems
It's not necessarily the word appearing in more than 50% of thre records. If you search result returns more than 50% of the records, mysql considers the result irrlevant and doesn't return anything. You can kind of test it by using LIKE. SELECT count(*) from table where field like %dealer% or field like %contact% Remember, by default full text will find records that contain any of the words you are searching on. If you want to find only records that contain all the words, you need to do full text boolean search. - Original Message - From: Taco Fleur [EMAIL PROTECTED] To: mysql@lists.mysql.com Cc: 'Brent Baisley' [EMAIL PROTECTED] Sent: Wednesday, June 21, 2006 8:51 AM Subject: RE: Full-Text problems Is there any way to test this?

RE: Full-Text problems
Is there any way to override this functionality? It becomes a real pain, I have to start doing weird stuff to overcome this limitation, if it would just return the results whether its more than 50% or not, I would be fine. Is there no way to do this? Thanks.
