Filters reduce the search space to a subset of the documents in the

i think cluster by md5 is more appropriate.
Do you want to cluster them by MD5 perhaps, but still return multiple
documents back from a search?
i want to return just the 1st image (the more relevant one). no use to
show duplicates in an image search app.
Now you've just said the same conflicting thing a different way. You
want to cluster but only return one. :)
If you only want one image returned, then it seems that only indexing
the same image once is the way to go. When you find a duplicate MD5,
don't index that as a second document. You will, instead, update the
document by adding additional ALT text and perhaps the additional URL.
Is there a reason why indexing each unique image (by MD5) is not a
good way to go in your case?
in sql this would be:
select distinct md5, url, alt from table group by md5 order by
score asc;
This would give you multiple records for the same MD5. You said
above you only want one per MD5.
