Anyone know a page-based search engine script that could locate a simple search string on multiple pages (4 or 5) of a site and then take you to the page the result is on and highlight it? I know it's possible.

I've been working on a floorplan-based printer mapper for the company I work at. That part works fine but I'd like to enhance it with people search capability. The idea is if I put text boxes with people's names over all the offices on the map then a text search script should be able to zero in on that person's name and show where they are. Simple but effective, that is if I can find the right search script. Can anyone recommend one? Thanks.
