This is the table. CREATE TABLE `posts` ( `post_id` int(20) NOT NULL AUTO_INCREMENT, `post_archived`

This is some sample data I am working on:

This query works as expected, giving one result.

SELECT * FROM posts WHERE MATCH( post_title, post_domain, post_url, post_content, post_tags ) AGAINST ('%26upsilon%3B+%26alpha' IN BOOLEAN MODE)

While this one fails to return anything than an empty result set.

SELECT * FROM posts WHERE MATCH( post_title, post_domain, post_url, post_content, post_tags ) AGAINST ('%CE%B5%CF%81%CF%89%CF%84%CE%AE%CF%83%CE%B5%CE%B9%CF%82%2C' IN BOOLEAN MODE)

I am baffled because it seems that including a proper string of characters in the string constant for AGAINST makes is work while using solely a Urlencoded string on its own does nothing.

Anyone come across this ?

http://dev.mysql.com/doc/refman/5.0/en/fulltext-natural-language.html

The MySQL FULLTEXT implementation regards any sequence of true word characters (letters, digits, and underscores) as a word. That sequence may also contain apostrophes (“’”), but not more than one in a row.

So: the first probably looks for ’26upsilon’ & ’26alpha’ (no 2B as it’s below the minimum word length), %s are not considered part of a word. Your second search treats ‘%’s as a separator, which results in all ‘words’ mysql recognizes being under the minimum word length. Urldecode your contents if possible, or use LIKE for specifix searches.

An illustration:

CREATE TABLE f (t varchar(255), FULLTEXT INDEX(t));
INSERT INTO f values('%foobar%fozbar%foxbar%');
INSERT INTO f values('%fo%fz%fb%');

SELECT * FROM f WHERE match(t) AGAINST ('foobar%foxbar' IN BOOLEAN MODE);
1 Result, so % is a word delimiter
SELECT * FROM f WHERE match(t) AGAINST ('fo%fz' IN BOOLEAN MODE);
O results (minimum under 4 chars
SELECT * FROM f WHERE match(t) AGAINST ('"fo%fz"' IN BOOLEAN MODE);
O results (minimum under 4 chars)
SELECT * FROM f WHERE match(t) AGAINST ('+fo +fz' IN BOOLEAN MODE);
O results (still that pesky minimum)
