Removing duplicates during a query

2013-08-22 Thread Dan Davis 
Suppose I have two documents with different id, and there is another field,
for instance content-hash which is something like a 16-byte hash of the
content.

Can Solr be configured to return just one copy, and drop the other if both
are relevant?

If Solr does drop one result, do you get any indication in the document
that was kept that there was another copy?

OK - I see that this can be done with Field Collapsing/Grouping.  I also
see the mentions in the Wiki for avoiding duplicates using a 16-byte hash.

So, question withdrawn...
