MySQL Fulltext search always has 0 results?

Question

I have read that using fulltext searching is faster then using LIKE %%. I have updated my script but it always seems to always have 0 results.

SELECT *,
MATC         


        

Answer 1

Fulltext search has some bizarre quirks.

For example, the behaviour described in the last paragraphs of this page could be the reason for your problem:

.... for example, although the word “MySQL” is present in every row of the articles table shown earlier, a search for the word produces no results:

mysql> SELECT * FROM articles
    -> WHERE MATCH (title,body) AGAINST ('MySQL');
 Empty set (0.00 sec)

The search result is empty because the word “MySQL” is present in at least 50% of the rows. As such, it is effectively treated as a stopword. For large data sets, this is the most desirable behavior: A natural language query should not return every second row from a 1GB table. For small data sets, it may be less desirable.

The answer here would be to add more rows, or use boolean search.
