Thanks for the suggestion Oleg, Would the rid be unique in this case? Would this be a better key to use? All the objects returned are my own ZClasses so alternatively I could add a property which I could make sure is unique for all items. Any thoughts anyone?

I'm doing quick search using several indexes in a ZCatalog as below

This works really well. However, if my query string is found in more than one index I get the same object returned more than once.
How do I sort the list of objects returned and more importantly remove duplicate objects?
Put all results in a dictionary, mapping URL to object. Do it in Python Script, of course.
Oops, forgot to say, that even this does not guarantee uniquness. Consider these URLs: http://my.server/Folder http://my.server/Folder/ http://my.server/Folder/index_html 3 different URLs point to the same object.
