json - Filter on multi match ES PHP

Solution:

The multi_match query must be located inside bool/must:

public function search_data_into_index($array)
{
    $params = [
        'index' => 'skills',
        'type' => 'people',
        'body' => [
            'query' => [
               'bool' => [
                  'must' => [  
                     'multi_match' => [
                        'query' => 'react',
                        'fields' => [$array[2]],
                        'fuzziness' => 'AUTO',
                     ]
                  ],
                  'filter' => [
                     'geo_distance' => [
                        'distance' => '300m',
                        'location' => '-25, -49'
                     ]
                  ]
               ]
            ]
        ]
    ];
    $response = $this->client->search($params);
    print_r($response);
}

Solution:

You need to combine multiple queries using boolean query

In JSON format your query will look like

{
  "query": {
    "bool": {
      "must": {
        "multi_match": {
          "query": "react",
          "fields": [$array[2]]
        }
      },
      "filter": {
        "geo_distance": {
          "distance": "300m",
          "location": [
            "-25, -49"
          ]
        }
      }
    }
  }
}
