Subject How to query for similar documents before indexing
Date Mon, 10 May 2010 20:39:34 GMT

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
