facet on field aliases of same field
Hi, we have a use case where we are trying to create multiple facet ranges based on a single field.
I have successfully aliased the field by using the fl parameter e.g. fl=date_decade:date,date_year:date,date_month:date,date_day:date where date is the original field and the day_decade etc are the aliases.
What I am failing to do is to create multiple facet ranges based on these aliased fields e.g:
&facet.field={!key=date_month ex=date_month}date_month&facet.field={!key=date_day ex=date_day}date&facet.range={!key=date_decade ex=date_decade}date_decade&facet.range={!key=date_year ex=date_year}date_year&f.date_decade.facet.range.start=1600-01-01T00:00:00Z&f.date_decade.facet.range.end=2000-01-01T00:00:00Z&f.date_decade.facet.range.gap=+10YEARS&f.date_year.facet.range.start=1600-01-01T00:00:00Z&f.date_year.facet.range.end=2000-01-01T00:00:00Z&f.date_year.facet.range.gap=+1YEARS"
We’re using Solarium here to generate the query and facet ranges but if we can do this in a raw HTTP request, that’s fine. I’m just not sure whether Solr will allow us to generate multiple facet ranges based on a single data field. Or am I approaching the problem in the wrong way?
Server is Solr 4.1
Any help appreciated

Thanks Michael. We’re looking into the use of localparams now.

RE: facet on field aliases of same field

It is indeed possible. Just need to use a different syntax. As far as I know, the facet parameters need to be local parameters, like this...
&facet.range={!key=date_decade facet.range.start=1600-01-01T00:00:00Z facet.range.end=2000-01-01T00:00:00Z facet.range.gap=%2B10YEARS}date&facet.range={!key=date_year facet.range.start=1600-01-01T00:00:00Z facet.range.end=2000-01-01T00:00:00Z facet.range.gap=%2B1YEARS}date
