Better to define color.not_null as a boolean field and always initialize as
either true or false.
But, even without that you need write a pure negative query or clause as
(*:* -term)
So:
select?q=*:*&fq=((*:* -color:[* TO *]) OR color:blue)
and
select?q=*:*&fq=((*:* -color.not_null:[* TO *]) OR color:blue)

Subject: How to query Solr for empty field or specific value
Hello,
I'm using Solr 4.2 and am trying to get a specific value (blue) or null field
(no color) returned by my filter query. My results should yield 3 documents (If
I execute the two separate filters in different queries, I get
2 hits for one query and 1 for the other).
I've tried this (blue or no color set):
select?q=*:*&fq=(-color:[* TO *] OR color:blue)
When that returned zero hits, I added a new field called "color.not_null"
and am setting it only if a color is defined (thinking there was a problem with
using the same field name).
select?q=*:*&fq=(-color.not_null:[* TO *] OR color:blue)
That too yielded zero results. Again, executing them separately does return
hits (3).
Does anyone see what I might be doing wrong? Thanks in advance, Kristian
