Please don't try to change history.  You're conveniently leaving out
part of the query.  An accurate quotation is this:

"""I'm looking for a function that allows me to do a binary search in a file.
   By binary search I mean searching for a sequence of bytes and not the binary
   search as in the Python Cookbook
   (http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/81188)

   Can anyone point me in the good direction?
"""

Now what part of the sentence starting with "By binary search I mean..."
is unclear to you?  He clearly (to me) is saying that although he's used
the term "binary search", he understands that it has a more standard
definition but that he *does not mean that definition* (and, we should
assume, he just couldn't think of another term for what he wants).
