Search Engines..

Hi ya'all....
I thought I saw a article about how search engines work... You know.. like when I type Beer, that it automatically searches for bear, and beer too....

I have made a search engine, but it only searches for the exact string.. Does anyone know or does anyone have an idea how to do the thing above ?

Thanks...

my guess would be to use some sort of a dictionary search and use the closest matching words.

Alright.. but how do I do something like that...

I read somewhere on this site, how to add MSOffice's dictionary to your apps, try searching for it

Thanks, I'll try that...
But I'm also looking how to do something like that in CGI/Perl... But I know I'm not on the right forum for that :-)

Well thanks again !

Raz.
