Hi Leo,

Please provide the output of EXPLAIN for your query (enclosed in [ code] [ /code] tags). Also remove the USE INDEX hints. By using these hints you take on some of the responsibilities of the optimizer, so you should only use them if you are not happy with the choices it makes.

Hope this helps,
