My company has recently purchased Windows Sharepoint Services and as
an end-user I'm quite
disappointed to learn that the default search functionality provided
by WSS is very limited.

Currently, my company is not considering SPS at all so I am curious
if anyone has integrated an
external search engine with Sharepoint so that users can search for
content that is stored in all
subwebs? And if yes, how did you do it? Was it difficult?
