[Zope3-Users] Getting values of catalog index in a given "context" ?

[Thierry Florac]

  Hi,

I'm using Zope3 catalog (with it's "zc.catalog" extensions and indexes).
What I'd like is to get a list of indexed values for a given index but
in a given context ; for that, I have :
 - a SetIndex which indexes content's path elements
 - a ValueIndex which indexes the content property that I'm looking for.

The SetIndex allows me to easilly find contents which are located in a
given subpath ; but is there a way to get distinct values of the
ValueIndex for these contents, without iterating over them explicitly
(because contents count can be quite huge !) ?

Thanks for any help,

  Thierry Florac
