"facet.mincount=0" returns facet values with 0 counts for "q=*" query

[Abhishek Sharma <ab...@unbxd.com>]

Hi,

Can any one help me understand what does it mean to have facet results like
this -

          "values": [
                "4th of july flags",
                0,
                "angela moore",
                0,
                "anklets",
                0,
                "applique flags",
                0,
                "army national guard",
                0,
                "bangles",
                0,
                "beatriz ball"
          ]

for a *q=** query with

*facet.mincount=0?*
What do the* results signify? *In what condition can we have *facet count
as 0* for *q=** query?

in general, a facet count of 0 means the term is in the index but does not 
match an of the docs in the result set.

if you are doing a query that matches all docs, and seeing facet values 
with a mincount of 0, that means the *term* is still in the index, but the 
documents that contained those terms have been deleted.

the tems themselves will be deleted if/when the segments containing them 
get merged away and the deleted documents are expunged.
