Multiple Must queries not working inside a should query as expected

[Venkat_Pavan]

I am trying to write a query of the form A or B or C or D where condition A is of the form A11 and A12, similarly B = B11 and B12 and so on. I am using elastic version 6.8 and executing the queries in Kibana. I have added "_name" to track which documents matched what conditions.

I am getting documents  with the following 

"matched_queries": [

      "A11",

      "C12",

      "B11",

      "C11",

      "D11",

      "D12"

    ]

My requirement is if a document satisfied condition A11 it must also satisfy A12. 
Same goes for others.
Thanks for the help :slight_smile: .

It looks like your document matched your logic correctly - C had both of the required 11s and 12s. The other reported half-matches for A and B are just added info you requested. If you are only interested in “x11 AND x12” match reporting shift the _name param up one level to the Bool that contains the 11 and 12 clauses and rename it to something appropriate eg b11&b12
