Is there a Boyer-Moore string search and fast search and replace function and fast string count for Delphi 2010 String (UnicodeString) out there?

Question

I need three fast-on-large-strings functions: fast search, fast search and replace, and fast count of substrings in a string.

I have run into Boyer-Moore string sea

Answer 1

Since I was just looking for the same: Jedi JCL has got a unicode aware search engine using Boyer-Moore in jclUnicode.pas. I have no idea how good or how fast it is yet.
