Elasticsearch query match + term boolean

Question

I have documents in elasticsearch index with a "type" field, like this:

[
  {
    "id": 1,
    "serviceDescription": "a bunch of text",
    "serviceTitle": "title",
    "serviceTags":["tag1","tag2"]
    "type":"service"
  },
  {
    "id": 2,
    "companyDescription": "a bunch of text more",
    "companyTitle": "title",
    "companyTags":["tag1","tag2"]
    "type":"company"
  },...
]

I want to run a match query across all docs in my index, like this:

body = {
    "query": {
        "match": {
            "_all":"sequencing"
        }
    }
}

but add a filter to only return results where the "type" field equals "service".

do you want to search for sequencing query string across all the fields of documents? Can you please explain add a filter to only return results where the "type" field equals "service". — ESCoder

As far as I can understand your question, you want to query for sequencing query string, across all the fields, for that you can use the multi_match query that builds on the match query to allow multi-field queries.

If no fields are provided, the multi_match query defaults to the index.query.default_field index settings, which in turn defaults to *. This extracts all fields in the mapping that are eligible to term queries and filters the metadata fields. All extracted fields are then combined to build a query.

Search Query:

    {
  "query": {
    "bool": {
      "must": [
        {
          "multi_match": {
            "query": "bunch of text"
          }
        }
      ],
      "filter": {
        "term": {
          "type": "service"
        }
      }
    }
  }
}

Search Result:

"hits": [
      {
        "_index": "64867032",
        "_type": "_doc",
        "_id": "1",
        "_score": 0.8630463,
        "_source": {
          "id": 1,
          "serviceDescription": "a bunch of text",
          "serviceTitle": "title",
          "serviceTags": [
            "tag1",
            "tag2"
          ],
          "type": "service"
        }
      }
    ]
