RiSearch PHP is a fully functional search script for small to medium sites and is fast enough to search 5000-10000 of pages in less then one second. RiSearch is an indexing search engine, which means that it will index your site first and then create a database with all words from your pages for faster search. Risearch provides a full-text search script and an index of all words contained within a document except small words and common words (this can be defined in the config file).
RiSearch can create an index using either binary files or MySQL which allows for a great deal of flexibility.
