limiting full text mysql searches to exact matches

问题

I am trying to match a table with keywords against a text. Problem is, that the query does not return exact matches, but only the most relevant ones:

    SELECT name, name_safe, MATCH name AGAINST ('".$ad['text']."') as importance
    FROM $T2
    WHERE MATCH name AGAINST ('".$ad['text']."') AND cat_type = 4
    ORDER BY importance DESC
    LIMIT 1

$T2 contains keywords like

hunde welpen
chihuahua

I only want the query to return a hit if it is an exact match. So a search for "welpen" should not return a result.

Thank you for any help.
