how to get all unique documents based on keyword feild
Hi ALL,
First thnx for spending time to read the message.
Am using MatchAllDocsQuery to get all the documents .
But i need documents that are unique based on keyword .
in my document keyword feild had values like 1,2,2,3,4,5,5,5,5 so on.....
so the result i need is only 1,2,3,4,5 so on ... unique
but MatchAllDocsQuery will get all documents 1,2,3,4,5
Do i have any class ,where i will get unique documents based on keyword.

I've never used it, but from my reading of the thread referenced
below, that is exactly what DuplicateFilter does: remove duplicates at
query i.e. retrieval time, based on whatever you tell it.

Hi Ian,
Tnx for the reply .
But i have already duplicate records and the issue is not for controlling
duplicate documents, but when i retreive documents
i should get unique documents based on keyword feild.

DuplicateFilter may be what you're looking for.
