neteagle Posted June 18, 2006 Share Posted June 18, 2006 I want to do a full_text search query.SELECT * FROM `product` WHERE MATCH (`product_name`) AGAINST ('Flower')With this query, I got some results,but when I changed 'Flower' to 'flower', I got nothing.It seems full_text search function case sensitive.How can I fix it?

poirot Posted June 18, 2006 Share Posted June 18, 2006 [!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]By default, the search is performed in case-insensitive fashion. However, you can perform a case-sensitive full-text search by using a binary collation for the indexed columns. For example, a column that uses the latin1 character set of can be assigned a collation of latin1_bin to make it case sensitive for full-text searches.[/quote][a href=\"http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html\" target=\"_blank\"]http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html[/a] Link to comment https://forums.phpfreaks.com/topic/12302-is-full_text-search-case-sensitive/#findComment-46998 Share on other sites More sharing options...
fenway Posted June 18, 2006 Share Posted June 18, 2006 Actually, this has nothing to do with fulltext searching per se, but rather how MySQL treats individuals columns for all types of comparisons; it is ultimately dependent on the collation.

neteagle Posted June 18, 2006 Author Share Posted June 18, 2006 My collation is UTF8-bin. I want the search to be case-insensitive. How can I do that?
