Hi, I'm using the grouping feature of Solr to return a list of unique
documents together with a count of the duplicates.
Essentially I use Solr's signature algorithm to create the "signature"
field and use grouping on it.
To provide good numbers for paging through my result list, I'd like to
comp
l number of facets as well.
I'm using Solr 3.5 (upgraded from Solr 3.4 without reindexing).
Thanks,
Michael

Hi, I've been wondering why some of my queries did not return the
results I expected. A debugQuery resulted in the following:
"java"^0.0 OR "haskell"^0.0 OR "python"^0.0 OR ("ruby"^0.0) AND
(("programming"^0.0)) OR "programming language"^0.0 OR "code
coding"^0.0 OR -"mobile"^0.0 OR -"android"^0.0

You're right in that case it's the whole query. P

That's exactly what I'd expect, but the problem is that "ruby" is
marked as mandatory, that i

It seems to be not the case. But you could append the fields Parameter
in the solrconfig.xml:

Our Solr started to throw the following exception when requesting the
facets of a multivalued field holding a lot of terms.

Hi,
is there an easy way to get the matches of an OR query?
If I'm searching for "android OR google OR apple OR iphone OR -ipod",
I'd like to know which of these terms document X contains.
I've been using debugQuery and tried to extract the info from the
explain information, unfortunately this is

I was comparing Queries with "debugQuery" enabled and disabled. The
difference was 60 seconds to 30 seconds for some (unusual) large
Queries (many Terms over a large set of documents chosen by filter
