Subject: [Zope-Coders] Proposal for minor ZCatalog improvement


> All ZCatalog indexes are using the id of the indexes to index attributes
> with the same name. ZCTextIndex introduced a new approach by seperating
> the id of the index from the attribute name to be indexed. This is a nice
> idea and allows to have different indexes on the same attribute name
> (e.g. having a FieldIndex and a text index on a string attribute).
> 
> I propose add this functionality to all Zope indexes. All interface for
> pluggable indexes should get a new method getIndexedAttribute() that
> returns the name of the attribute that will be indexed by this index.
> The indexes tab of the ZCatalog should be modified to display the
> indexes as:
> 
> topic_txt  (TextIndex on topic) ...
> topic_field (FieldIndex on topic)
> 
> For backwards compatiblity getIndexedAttribute() would  return the
> id of the index if the indexes has no dedicated attribute to keep
> the name of the indexed attribute.
