javascript - Dynamically retrieve all fields present in Solr documents -

-



is possible dynamically retrieve fields present in set of solr documents , still maintain reasonable performance? end goal here dynamically populate list of numeric fields users sort current query upon.

in perfect world, i'd able have list contain of numeric fields present in docs returned user's query.

if isn't possible achieve, though, i'm going populate list numeric fields via luke handler. unfortunately seems luke handler returns fields entire collection, can't restricted current query.

i'm new solr, help/discussion appreciated!
