You might take a look at the search engine in SCAN. It uses a fulltext index and
is able to search for text in specific fields of items. Items in SCAN are
versioned, and if a word occured in an earlier version of an item but not in the
current, that earlier version is presented.
For searching, it's pretty fast. The indexing that's necessary when items are
added is a bit slower, but still acceptable. One day I'll make it fast enough
that indexing the whole contents of source files becomes feasible (which
currently isn't...)

Look at http://squeak.heeg.de:8080/search and the 'Searching' help page
accessible from there.

The whole SCAN source is downloadable from SCAN, too. Building a Swiki on top of
the SCAN primitive structure shouldn't be too difficult, but it's not on my
agenda.
