I think Daniel was talking about the full text search of all pages. This index for this was built by the Microsoft Help Compiler so it was available in CHM help; the Mac has the full text search available in lots of places, so it worked there just because the system automatically indexed the static HTML pages.

I think it would be nice to get this back and make it less platform specific. It would need indexing of the content of the pages, and Javascript or similar to access the indices.
