Faceting json response - odd format
Hello,
Relatively new to SOLR, I am quite happy with the API.
I am a bit challenged by the faceting response in JSON though.
This is what i am getting which mirrors what is in the documentation:
"facet_counts":{"facet_queries":{},
"facet_fields":{"metadata_meta_last_author":["Nick",330,"standarduser",153,"Mohan",52,"wwd",49,"gerald",45,"Riggins",36,"fallon",31,"blister",28," ",26,"morfitelli",24,"Administrator",22,"morrow",22,"richard",22,"egilhoi",18,"USer Group",16],
This is not trivial to parse - I've read the docs but can't seem to figure out who one might get a more structured response to this.
Assuming I am not missing anything, I guess i have to write a custom parser to build a separate data structure that can be more easily presented in a UI.
Thank you
Cord

: What i would prefer to see as we do with all other parameters is a
: normal key/value pairing. this might look like:
a true key value pairing via a "map" type structure is what you get with
json.nl=map -- but in most client langauges that would lose whatever
sorting you might have specified with facet.sort.
: {"metadata_meta_last_author":[{"value": "Nick", "count": 330},{"value":
: "standard user","count": 153},{"value": "Mohan","count":
: 52},{"value":"wwd","count": 49}…
that structure is essentially what you get with json.nl=arrarr -- ie: the
values are still in the specified facet.sort order; but instead of an
array of maps, it's an array of array "pairs".
This is the most close equivilent to how the facet counts are internally
modeled -- you should be able to inject those keys you choose ("value" and
"count") in your client layer fairely easily.

You didn't provide any specifics about what you felt was problematic, but
i'm guessing what you want to do is pick the value you think is best for
the "json.nl" param...
