Get the number of occurrences of found matches in fulltext search?

[tyncseecto7u4]

I am curious whether in a regular fulltext search:\[code\]mysql_query("SELECT post_subject,topic_id,forum_id,post_text FROM phpbb_posts WHERE MATCH (post_subject,post_text) AGAINST ('".$dtitle."') GROUP BY post_subject LIMIT 50") or DIE(mysql_error());\[/code\]I am able to get the result of number of found matches to sort by.So I could do something like \[code\]ORDER BY number_of_keywords desc\[/code\]
