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?
I have a ZClass with a 'lines' type property (a list) called course_logs If I then search using: <dtml-in "Catalog(course_logs='Feedback')"> This returns all catalog entrys which contain 'Feedback' as one of the course_logs elements. This is essential for building many-many relationships. -- ___ // Zen (alias Stuart Bishop) Work: zen@cs.rmit.edu.au // E N Senior Systems Alchemist Play: zen@shangri-la.dropbear.id.au //__ Computer Science, RMIT WWW: http://www.cs.rmit.edu.au/~zen
