Search Engine with PHP

 

    Hi all-

 

I'm making an internal search engine with PHP.

So far, the user enters keywords and the database is searched with:

 

SELECT ... WHERE lower(fieldname) LIKE lower(keyword1) AND lower(fieldname) LIKE lower(keyword2)...

 

and this works great.  Although, now I want the answers diplayed in order of best match (not sorted just by a fieldname).  How do I do this?  Do I need to totally restructure the search engine?  Can I do it with a count( ) function?  If so, how? 

 

Any help would be great.

Thanks,

Mike
