這種問題怎麼解決？

我使用drupal 6.6。收到空間商通知：
We have detected that your account executing a slow MySQL queries.
MySQL Query: select t.word as realword, i.word from search_total t left join search_index i on t.word = i.word wh
Slow MySQL queries are not allowed, because you share server resources with thousands of other users and your long MySQL queries are slowering the server and other users are having MySQL performance and connectivity problems. Please optimize your MySQL queries as soon as possible.
Here are some good articles how to optimize MySQL queries: http://www.google.com/search?q=optimize+mysql+queries
Good tips how you can optimize your scripts and make our servers run faster:
- disable visitors monitoring and tracking (each move of your visitor makes database query)
- disable all unused modules
- disable internal stats for your website - use http://www.google.com/analytics/ for example
請問「MySQL Query: select t.word as realword, i.word from search_total t left join search_index i on t.word = i.word wh」是什麼問題？怎麼解決？
