Hi Erick, I am able to achieve querying on Collection3 with INNER JOIN between two document types and JOIN across collection1 using below mechanism. I am also getting facetting information from collection3 along with data.
http://localhost:8983/solr/collection3/tcfts?wt=json&indent=on&start=0&rows=50&q.op=AND&q=OC2:(9350) AND _query_:"{!join from=col3_Oc1 to=Oc1}ID1:xtWNf_fTAaLUgD" AND _query_:{!join to=col3_Field1 from=Field1 fromIndex=collection1}Field2:12010340 Now, I want to collect the faceting information for collection1 with the same type of query but no data. So what is needed is - Query on collection1, match few columns with some expression and then do JOIN across collection3 do INNER JOIN as above. Could you help on this? -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
