I know I will probably need the _msearch API to do this but am having trouble accomplishing my goal.
I have two indices (Index1 and Index2) that each have a term I am trying to correlate. Basically, I want to find documents where Index1:TermA = Index2:TermB.
I have tried using the following:
GET /Index1,Index2/_search { "query": { "bool": { "should": [ { "term": { "TermA.keyword": "*" } }, { "term": { "TermB.keyword": "*" } } ] } } }
