Limit the number of rows a fuzzy search returns

At times, you might find that the search engine returns more information than you require. Use the MAX_MATCHES and WORD_SCORE tuning parameters to limit the number of rows that the search engine returns.

For example, suppose that, when you execute the following query, the text search engine takes a while to return 100 rows, although you are interested in the first three: 
SELECT id, description FROM videos
    WHERE etx_contains(description,
    Row('multimedia document editor' , 
        'PATTERN_TRANS & PATTERN_SUBS'));
