Subject Re: Newly observed Facets
Date Tue, 20 Jan 2015 17:59:47 GMT
ok. So I am trying this query:

http://cluster1.com:8983/solr/my_collection_shard4_replica1/select?q=*%3A*&rows=0&wt=json&indent=true&facet=true&facet.field=userName&fq=startTimeISO:[NOW-1DAY%20TO%20NOW]&fq=-_query_:%22{!join%20from=%
 userName%20to=%userName}startTimeISO:[NOW-30DAYS%20TO%20NOW-1DAYS]%22

This query is giving me results. I will now validate it.

Just to confirm, Is this the right query that I am using? Please correct me
if I am wrong here.
