MySQL can use an index if your query looks like
foo LIKE 'abc%'orfoo LIKE 'abc%def%'. It can use the index for any portion or the string before the first wildcard. If you need to match a word anywhere within a string, you might want to consider usingFULLTEXTindexes instead.More detail on indexes: http://dev.mysql.com/doc/refman/5.1/en/mysql-indexes.html
