Zope 2.1.6 contains a minor bug for "and not".
Patch coming soon.

I think, I can provide soon (Tuesday/Wednesday) a patch
that allows for proximity searching.
The code is almost ready: rather than remembering the
text information, it remembers the object and extracts
the text on demand.
The code currently fails, if the object no longer exists
or is a "Local File System" object (which can not truely be
remembered in an IOBTree).
Thus, I need to add some exception handling, and test
a bit.
