By "binary content", I'm going to assume that you literally mean searching
for any binary string of data (as opposed to textual).

Do many engines out there generate useful indices without tokenization
patterns? Given binary content, are there any tokens generate an index from,
a la natural language words or characters, or patterns (in images, music,
etc.) which would work? If so, you might want to generate an index of
the repository (via post-commit hook, periodic background processesing, or

If not, you could use a primitive solution like grep'ing a checkout of a
specific rev of the repository, or a more hands-on approach like a crawler
which searched on-demand, walking the repository based on a specified tree
and revision range, re-assembling each revision and searching it.
