12000 picts : slow search query

[antisa33]

Hello, in cpg_picures i have 12000 pictures.
i can see on my server than in search.php, the query is very slow because the search.php must look in 12000 lines, and give juste a few result.
How can i optimize this ? Is it possible ?
Thank you for all

The more complex your search is the longer it'll need. If you just search in the indexes (title, caption, keywords, filename) it should be pretty fast. Do you have a link so that I can have a look?
