mysql full text

[AN-net]

ok its giving me the error can not find fulltext index in column list. but in phpmyadmin its listed under indexes as fulltext.

here is my code:

PHP Code:

$query['where'] = "MATCH (news.news_title,news.news_text) AGAINST ('".addslashes($searchfor)."') AND news_active=1"; 


that is my where query

also does it automatically order them by relevancy and how do i change those relevancy values to percentages?
