You can use IntraSearch for smaller and medium websites. A database is not needed. The website will be crawled from the defined baseurl.
The links will be collected and the content cached – so future searches are faster.
Already succeeded searches are stored in files too to increase search speed.
The textparts with the found searchstrings are cropped in the search results so only the part with the searchstring is displayed (like displaying the results on Google)
Various options help you to handle Live Search. A Search Word Cloud is available too.
