Problem slow search

I have problem with search module in my opencart here: http://www.newannashop.it
it take like 30 seconds for each search

someone can help me , to find the issue?

ps. i dont edited source code, would be nice maybe a new search.php that find just in description or title becose there are more of 1000 products

might be issue with database table creation or index missing. It might be a place to start. Do you see any errors in logs ?

Slow search is often helped by running the database queries detailed in this thread:
