[PHP] site search engine.. not dynamic

[Aaron Wolski]

Hi all,
 
Can anyone point me in the direction of a site search engine that reads
files in a directory find relevant results for an search term that a
person might enter on a site?
 
I need to build a site search engine but the problem is. the site isn't
dynamic (yet) so I need to read actual files to pull things together.
 
Anything out there?
 
Thanks!
 
Aaron
