i search for a possibility to query a catalog like this:
catalog({'meta_type':myobjecttype, [x for x in 'keyword-index' if x.find(mysubstring) != -1]})
Description: there is a metadata (keyword index) for urls in my catalog and i have to know the catalogentries with a matching substring in this keyword-index
Example: catalog-entry1 -> ['/abc/def/123', '/ghi/123'] catalog-entry2 -> ['/ghi/123', '/abc'] catalog-entry3 -> ['/xyz/def/123', '/ghi/123'] and i search with '/abc' and wanna get entry1 and entry2
The form of query you created above is not supported by zcatalog. To get the results you seem to be looking for I suggest that you create a ZCTextIndex and do a wildcard suffix search. eg. (search in python script) searchterm = 'abc*' searchresults = Catalog.searchResults({'newtextindex' : searchterm}) for res in searchresults: do something with results... where, 'newtextindex' is a ZCTextIndex which was built using your metadata.
