[Zope] Use of ZMI Find Tab

[Eric Roby]

Is it possible to perform searches via the find tab (advanced search
input form) for occurrances of text in ZClass properties?  I have
searched the docs and listings for hints but nothing specifically says
this can be done. It is also unclear regarding the limitations of the
expression box.  The source (FindSupport.py) appears to set up an eval
call so I am not sure how best to setup an expression that would work
here.  Also, the source looks to set up a special handler for ZClass
meta_types (grabbing propertysheets.methods), so I am confused whether
this can be accomplished via this service or will I have to setup my own
using zopeFind?

TIA
