How to Optimize MySQL LIKE Queries with Wildcards?

Optimizing MySQL LIKE Queries with Wildcards

When dealing with LIKE queries involving wildcards (e.g., '%test%'), the performance of MySQL can suffer. To address this issue, there are techniques to enhance the performance of such queries.

MySQL can leverage an index for LIKE queries that conform to the pattern 'foo LIKE 'abc%' or 'foo LIKE 'abc�f%'. This is possible because the index can utilize the string portion preceding the first wildcard. However, if the goal is to match a word anywhere within a string, considering FULLTEXT indexes may be a viable alternative.
