I've written previously that I've been hunting for a decent way to do web site search (specifically for CMS 2002 but just in general too...). I have been looking at Lucene.NET (which is in .TEXT 0.96) and a few other options. One interesting (and low cost - $39.99) option seems to be this. Essentially it provides a web crawler extension for Index Server, anyone tried this, any other options for low cost site search (as distinct from DB search / file-system based ones) I should consider?
