Regular expressions: I do not think so. I can recall a recent discussion on
this topic.
Boolean: Google searches a boolean space if I remember correctly, but the
use of pluses, minuses and the like appears rather weak. Altavista, who
used to have good support for this rich syntax, are generally weak at
providing good results.

Judging by the queries that I see, nobody ever uses them. Far less than 1%
as a matter of fact. I gave up on it myself.

I would love to see a regular expression search on the Web. It can be a
priceless resource for programmers or for those who do ancestry (or just
arbitrary names) searches. Algorithms exist, e.g. D-M Soundex, but they are
just too computationally expensive to search the entire Web with.
