Search Engine

Hi,
Speaking of the search techniques, I have a small client with a static shop-like website who wants search abilities for a CD catalog.  There is no database available, but PHP is operational.

Is there any PHP library or tool that would allow me to search the site without a database?  Some leads would be appreciated.

Thanks,
Stephen

I'm not sure about synonyms, but support for misspelled words can
typically be
achieved with the Levenshtein algorithm, and PHP supports that:

Hope that helps.
