Ned Sturzer has developed a new search engine for the Hebrew Bible (Leningrad Codex B19a), called Masorah Engine (please note that the site can only be viewed correctly with Internet Explorer — Neither Firefox nor Safari worked for me).

This engine (requiring Windows XP or better) is able to search for the Hebrew vowel marks (nikudos) and tropes (te’amim) in many different and rather complex ways, so you may want to take a look. There are a number of screen shots available, but no demo version.
