: <uniqueKey>id</uniqueKey> : <defaultSearchField>document_title</defaultSearchField> : <copyField source="document_title" dest="id"/>
whoa... that's a pretty out there usecase ... i don't think i've ever seen someone use their uniqueKey field as the target of a copyField. off the top of my head, i suspect maybe the copy field is taking place after the duplicate detection? ... but i'm not sure... : When I add a document with a duplicate title (numeric only), it does not : get duplicated ...and now i'm *really* not sure, that doens't make much sense to me at all. : I can ensure duplicates DO NOT get added when using the field type : 'string'. hmm... could you perhaps add the value directly to your "id" field (string) and then copyField it into document_title ? based one what youv'e said, thta should work -- although i would agree, what you describe when using your current schema definitely sounds like a bug. it would be great if you could open a Jira issue describing this problem ... it would be even better if after posting the issue you could make fixing it easier by attaching a test case. :) -Hoss
