Hi Ed.

Yes. In the background, the search engine indexes files in certain folders (you can usually configure which folders), so when you do a search, it looks in the index to quickly find files containing the search string.

I haven't seen it, but Paul Mrozowski is doing a session on Lucene.NET at Southwest Fox (http://www.swfox.net/sessions.aspx#Full_Text_Search_using_Lucene.NET). Also, Advantage Database Server has a built-in text search engine that's blindingly fast and works with VFP tables.
