Facets referenced by key

[Brendan Grainger <br...@gmail.com>]

Hi All,

I'm creating 2 distinct sets of facet results using a key local param, e.g.:

facet.field={!ex=dt key=my_facet_key}the_facet_field&facet.field={!ex=dt
key=some_other_facet_key}the_facet_field

I would then like to refer to these 'pseudo' field later in the request
string. I thought this would be how I'd do it:

f.my_facet_key.facet.prefix=a_given_prefix

and

f.my_other_facet_key.prefix=a_different_prefix

So the whole thing would look like (With as similar request string for the
my_other_facet):

facet.field={!ex=dt
key=my_facet_key}the_facet_field&f.my_facet_key.facet.prefix=a_given_prefix


I thought this would work, however it doesn't appear to. What does work is
if I define the prefix and mincount in the local params:

facet.field={!ex=dt key=my_facet_key
facet.prefix=a_given_prefix}the_facet_field

Is this expected? I'm also using sunspot and they construct the queries
with keys as in my first example, i.e. facet.field={!ex=dt
key=my_facet_key}the_facet_field&f.my_facet_key.facet.prefix=a_given_prefix


Thanks
Brendan

Thanks for the excellent clarification. I'll ask the sunspot guys about the localparams issue. I have a patch that would fix it

Thanks 
Brendan

	...


that syntax was proposed in SOLR-1351 and a patch was made available, but 
it was never commited (it only supported a subset of faceting, needed more 
tests, and had unclear behavior about how the defaults where picked if 
you combined f.key.facet.foo + f.field.facet.foo + facet.foo)

: I thought this would work, however it doesn't appear to. What does work is
: if I define the prefix and mincount in the local params:
: 
: facet.field={!ex=dt key=my_facet_key facet.prefix=a_given_prefix}the_facet_field

Correct, SOLR-4717 added support to Solr 4.3 for specifying all of the 
facet options as local params such that that syntax would work.  Given th 
way the use of Solr and localparams have evolved over the years it was 
considered a more natural and logical way to specify facet option on a per 
field or per key basis.

: Is this expected? I'm also using sunspot and they construct the queries
: with keys as in my first example, i.e. facet.field={!ex=dt
: key=my_facet_key}the_facet_field&f.my_facet_key.facet.prefix=a_given_prefix

I can't comment on that ... i'm not sure why sunspot would assume that 
behavior would work (unless someone looked at SOLR-1351 once upon a time 
and assumed that would definitely be official at some point)
