Have you tried using result grouping for your query? There are some very good examples in the wiki:

Note, I don't know what the value is, I just want to find all documents with duplicate values. For example, I have 5 documents: Doc1: field Name = Peter Doc2: field Name = Jack Doc3: field Name = Peter Doc4: field Name = Paul Doc5: field Name = Jack If I executed the query, it would find documents Doc1 and Doc3 (Peter is the same), and Doc2 and Doc5 (Jack is the same). Thanks, Peter
