Query not returning correct result

Elastic Stack Elasticsearch
1

My query below is returning an incorrect result. You can see that the "params" in the result do not perfectly match the terms params in the query. How do I craft my query so that the params must match perfectly?

The query:

GET _search
{
   "query": {
      "filtered": {
         "filter": {
            "bool": {
               "must": [
                  {
                     "term": {
                        "class": "ezr_ribbon_army"
                     }
                  },
                  {
                     "term": {
                        "award_sku": "401 ARACMR"
                     }
                  },
                  {
                    "terms": {
                      "params": [
                        "bronze-star|1",
                        "branch|army",
                        "type|standard_ribbons",
                        "spacing|flush",
                        "alignment|center",
                        "assembly|assembled",
                        "width|3"
                      ]
                    }
                  },
                  {
                    "term": {
                      "params_count": 7
                    }
                  }
               ]
            }
         }
      }
   }
}

The results:

the "params" in the result do not perfectly match the terms params in the query.

Were you expecting the terms filter to be an AND? It's an OR - see Elastic: Search Results | Elastic

"Filters documents that have fields that match any of the provided terms"

Thanks for opening my eyes to that. Clearly misread. So to change the default OR behavior of terms if I'm reading the docs correctly (https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-filter.html) this is the correct way to tell terms to use AND. It seems to be working now. Thank you for the heads up.
