Web robots are not search engines (just the things that fill the engines),
as far as I understand.
As I mailed to J. earlier, most searchengine algorithms aren't directly
compatible with (my)sql.
(Meaning that, for the best performance *you* have to do the searching, and
not mysql - once you have found records that you want to retrieve, you can
use sql to retrieve them. )
Here's some whitepapers about it:

(The first one has a lot of links to other, very interesting, papers.)
