Hoss Man commented on SOLR-911:
-------------------------------
bq. Well, it's optional... it's only an issue for stateless clients without
conventions or application specific knowledge - and they could always look at
the original parameters via echoParams.
that assumes it wasn't baked into the config file.
I guess there's no harm in adding it (except perhaps confusion: i'd hate to see
people assume that they can add "fq=key" since they got "key" back in the
facet_queries section of the response)
my point was really just that facet constraint "labels" are really only useful
if each label is easily associated with a way of applying that constraint.
replacing the query string with a "key" in the response is only useful if that
key can be used for something.
It seems to me like it would be far more useful to just reserve "key" as a
special local param that we guarantee will never get used, so people can
include it in the facet.query and then parse it out of the response themselves.
You can already do this today...

In Config...
<lst name="defaults">
<str name="facet.query">{!ignoredparam="Low Price"}price:[* TO 500]</str>
<str name="facet.query">{!ignoredparam="Hight Price"}price:[500 TO
*]</str>
...
In Query Response...
<lst name="facet_queries">
<int name="{!ignoredparam="Low Price"}price:[* TO 500]">3</int>
<int name="{!ignoredparam="Hight Price"}price:[500 TO *]">0</int>
...
{noformat}
...but it would be nice to have a parma name reserved for this.
(admittedly it never occurred to me until this Jira post that that worked, i'm
going to start encouraging every one i know to start doing that)
