If you're using a query with LIKE '%term%' the indexes can't be used. They can be used only if you use a query like 'term%'. Think about an address book with tabs, you can find really fast contacts starting with letter L, but to find contacts with a on somewhere in the word, you've to scan the whole addressbook.

The better alternative could be to use full text indexes:

CREATE FULLTEXT INDEX title_desc
ON table (title, description)

And then in the query:

SELECT title, description FROM table
WHERE MATCH (title, description) AGAINST ('+Pizza')
