Markus Thank you for your response That would be great if the index has the option to prevent duplicate from entering the index. But is it going to be a silent action ? Or will the add method return that it failed indexing because it detected a duplicate ? Is it commited to the 1.4 already ? Cheers matt

Based on that, it should be able to prevent new documents from entering the index. The first part works very well but i have some issues with removing those documents on which i also need to check with the community tomorrow back at work ;-) [1]: http://wiki.apache.org/solr/Deduplication Cheers, -----Original message----- From: Matthieu Labour <matthieu_lab...@yahoo.com> Sent: Mon 10-05-2010 22:41 To: solr-user@lucene.apache.org; Subject: How to query for similar documents before indexing Hi I want to implement the following logic: Before I index a new document into the index, I want to check if there are already documents in the index with similar content to the content of the document about to be inserted. If the request returns 1 or more documents, then I don't want to insert the document. What is the best way to achieve the above functionality ? I read about Fuzzy searches in logic. But can I really build a request such as mydoc.title:wordexample~ AND mydoc.content:( all the content words)~0.9 ? Thank you for your help
