Solr Faceting issue

[Smitha Rajiv]

Hi Solr Experts,


Request you to please help me in fixing the below facets problem. Thanks in
advance. Also pls let me know if you do not understand any part of my
explanation below.



How do I facet on more than two categories (let’s say ‘project’ and ‘type’
as discussed below) at the same time to get combination facets and their
count ?

When you open URL,    http://search-lucene.com/?q=facets you can see the
facets on right hand side as 'Project','type','date','author' and their
corresponding values with count in brackets.



For instance, let’s say you select *'solr(3366)'* under 'Project' facet,
still I can see other values under 'Project' facet like ElasticSearch etc.
along with their respective count.

Project:

                solr(3366) -- selected

                ElasticSearch (1650)

                Lucene (1255)

                Lucene.Net (43)

                Nutch (20)

                PyLucene (17)

                Mahout (16)

                ManifoldCF (8)

                Tika (4)

                OpenRelevance (3)

                Lucy (2)

type:

                mail # user (2791)

                issue (303)

                mail # dev (134)

                source code (82)

                javadoc (37)

                wiki (36)

                web site (2)



2. Further when I  Select 'mail # user(2791)' under “type” section , again
I can see other values under “type” section with their corresponding count
in brackets and their corresponding values in “Project” facet gets changed
accordingly (namely the count ).

project:

                Solr (2784) -- selected

                ElasticSearch (1056)

                Lucene (237)

                Lucene.Net (24)

                Nutch (14)

                Mahout (10)

                ManifoldCF (4)

                Lucy (2)

                OpenRelevance (1)

type

                mail # user (2791) -- selected

                issue (303)

                mail # dev (134)

                source code (82)

                javadoc (37)

                wiki (36)

                web site (2)



  Observe how solr(3366) changed to   Solr (2784) post selection of mail #
user along with the other values of ‘Project’ (like ElasticSearch etc.) and
‘type’ (issue, javadoc etc.,) with a change in their count values.



I want to achieve similar working functionality.  Can you pls let me know
if the below query is in the correct direction. Pls let me know if I have
to modify this. if yes, what and how. Probably an explanation on why would
do a huge help.



http://localhost:8080/solr/collection1/select?q=solr%20facets&fq=Project%3A(%22solr%22)&fq=type%3A(%22mailhashuser%22)&facet=true&facet.mincount=1

&facet.field=project&facet.field=type&wt=json&indent=true&defType=edismax&
json.nl=map



If the above query is not in the correct direction. Pls help in
constructing the same. Thanks in advance.
