simple boolean query language that allows 'and', 'or', phrasing, parenthesized boolean expressions, and proximity matching. Except for proximity searching, it is all true. I was in error when I stated that proximity searching was supported. The code is there, buy the back end storage and references to the objects to do the proximity matching had to be ripped out of ZTables because of size constraints. You would have to create a meta-data table entry for your text content that was indexed which is not efficient at all for a minor feature. 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. Dieter
