[Zope-dev] Keyword Indexes in ZCatalogs

[Alexandre Ratti]

Hello,


Could someone explain how to use Keyword Indexes in ZCatalogs? In a 
ZCatalog, we now have 3 index types: Text Index, Field Indexes and Keyword 
Indexes.

Here is the information I have found so far about the Keyword type:

"Keyword Indexes index a sequence of objects that act as 'keywords' for an
object. A Keyword Index will return any objects that have one or more
keywords specified in a search query."
(source: Indexes tab of a Zcatalog)

"Keyword Index: Subclasses all of the field index behavior, except that
property values are treated as a sequence of keywords."
(source: posting on a Zope list)

Could someone provide an implementation example?


Thanks.

Alexandre
