Query an array that contain string with terms-CodePudding

I want filter result from Elasticsearch where array of strings contain one of specific string value:

This is current json result, no filtered :

{
            "id": 1,
            "title": "Title",
            "tags": [
                "tag filter"
            ],
},
{
            "id": 2,
            "title": "Title",
            "tags": [
                "different tag filter"
            ],
},

Objectif : obtain only result where tags contain simple "tag filter" What i made:

 $termsQuery = new Terms('POITypes');
 $termsQuery->setTerms($terms); // $terms => array("tag filter")
 $boolQuery->addMust($termsQuery);

What dd report:

SearchController.php on line 90:
Elastica\Query\BoolQuery {#892
  #_params: array:1 [
    "must" => array:1 [
      0 => Elastica\Query\Terms {#893
        #_params: array:1 [
          "tags" => array:1 [
            0 => "tag filter"
          ]
        ]
        #_rawParams: []
        -field: "tags"
      }
    ]
  ]
  #_rawParams: []
}

When i add this must filter with this terms requirement, there are 0 result obtain. I found no solution since 2 days for this simple query... what's wrong with my code ?

Expecting only result where tags array includes one of my terms values.

CodePudding user response：

Pass field name as tags.keyword.

Tags field is of type "text" so your query is trying to match "tag filter"against individual tokens["tag","filter"], you need to match it against full value.

If index was auto created , it will have keyword subfield by default, otherwise you will need to create it.
