If the value is aquired, then it means that this object has that value,
aquired. I find it logical that the indexing will behave like that too, and
I'm pretty sure I have used it in some application.

Why is it a problem? It sounds like a feature to me. :-)
If you have an attribute that you don't want to be aquired, I guess you have
to make a computed attribute out of it.

RE: [Zope-dev] Catalog Text Indexing

[Bjorn Stabell]

I find it quite handy that it acquires the value.  I often define
"global" methods that I call in an acquired way.  For instance one could
be "MainTitle" which returns a part of the Title only (used to make
heads and subheads out of one Title).
