I was hoping to be able to do a join with 3 cores. I found this page that seemed to indicate it's possible?
https://stackoverflow.com/questions/52380302/solr-how-to-join-three-cores Here's my query: http://localhost:8983/solr/dbtrphon/select?indent=on&rows=1000&sort=score desc, id desc&q=(phone:*Meredith* OR descr:*Meredith*){!join from=debtor_id to=debt_id fromIndex=debt}*&fq={!join from=debtor_id to=debtor_id fromIndex=dbtr }(ssn1:12 OR ssn1:33) AND (assign_id:584 OR assign_id:583)&cursorMark=* { "responseHeader":{ "status":400, "QTime":14, "params":{ "q":"(phone:*Meredith* OR descr:*Meredith*){!join from=debtor_id to=debt_id fromIndex=debt}*", "indent":"on", "cursorMark":"*", "sort":"score desc, id desc", "fq":"{!join from=debtor_id to=debtor_id fromIndex=dbtr }(ssn1:12 OR ssn1:33) AND (assign_id:584 OR assign_id:583)", "rows":"1000"}}, "error":{ "metadata":[ "error-class","org.apache.solr.common.SolrException", "root-error-class","org.apache.solr.common.SolrException"], "msg":"undefined field: \"debtor_id\"", "code":400}} The schema for dbtrphon has debtor_id, the schema for debt has debt_id, and the schema for dbtr has debtor_id. These fields all should be able to join, but I get this error. I've tried substituting debt_id for the debtor_id in the second join, but I get the same error 'undefined field 'debt_id'. I am unsure what I'm missing? Thanks, Rhys
