Facet not working in Solr
Query parser = dismax
range query :
q=field:[a TO b]
DOESN'T WORK (Less important question. WHY?)
Query parser = Lucene
range query:
q=field:[a TO b]
WORKS
Query parser = edismax
range query
q=field:[a TO b]
WORKS
PROBLEM:
Facet:
with query parser
a) Lucene
b) Dismax
c) eDismax
DOESN'T WORK.

Any ideas ?

Well yes, Thank you so much.
I had lost that point of * in the main query.
With that I get what I expect.
This was awesome. Thanks so much

I think you are missunderstanidng the point of faceting.
when you ask for range faceting (or field faceting, or query faceting) the
counts are based on the result set of your main query -- the constraint
counts tell you how many of the *results* match each constraint.
If your main query matches 0 documents, then the constraint counts will
match no documents. if your main query matches 8 documents, then the
constraint counts will tell you, for each constraint, how many of those 8
documents match each constraint.
If you want to know how many documents, in your entire index, match each
facet constraint, then you need to use "q=*:*" (with the lucene or edismax
parsers) to tell solr that you want the entire index to be treated as your
main query.

Again to elaborate,
the documents all have an indexed field called u_height which is between
160.0 to 172.0
Range queries work on them with the lucene and edismax.
But faceting using the following URL gives numFound = 0, and all 0's in the
facet counts
q=&fq=&start=0&rows=100&fl=u_height,id,score&wt=&debugQuery=on&explainOther=&facet=on&facet.range.other=all&
*facet.range.start=160.0&facet.range.end=172.0*&facet.range.gap=2.0&*
facet.range=u_height*&facet.range.include=all&defType=edismax
Adding a value in q with qf set like so
*q=165.0&qf=u_height*
&fq=&start=0&rows=100&fl=u_height,id,score&wt=&debugQuery=on&explainOther=&facet=on&facet.range.other=all&facet.range.start=160.0&facet.range.end=172.0&facet.range.gap=2.0&facet.range=u_height&facet.range.include=all&defType=edismax
gives 8 documents as expected in numFound and facet count of 8 only in the
range of 164.0, whereas I would like to *get the facet counts of all the
ranges.*
Anything missing here?

Okay my bad for the lack of info :
- When I say doesn't work means numFound = 0
- Whereas range queries on the same fields give documents
- Even adding a value in q gives numFound = 0. using all 3 types of
parsers. Even if dismax doesn't support range queries. edismax and lucene
should give the result > 0, right?

: Query parser = dismax

dismax does not support range query syntax, it never has...

Define "DOESN'T WORK" ... what do you expect to get? what do you actaully
get? is there an error message?

you're q param is empty, so I unless you have other param defaults in your
solrconfig you haven't told us about, I suspect you are getting an error
about needing a q param -- which has nothing to do with faceting -- what
documents do you want to facet over?
