Match all query

Match all query

The most simple query, which matches all documents, giving them all a _score of 1.0.

$params = [
    'body' => [
        'query' => [
            'match_all' => [
            ],
        ],
    ],
];
$response = $client->search($params);

resp = client.search(
    query={
        "match_all": {}
    },
)
print(resp)

response = client.search(
  body: {
    query: {
      match_all: {}
    }
  }
)
puts response

res, err := es.Search(
    es.Search.WithBody(strings.NewReader(`{
      "query": {
        "match_all": {}
      }
    }`)),
    es.Search.WithPretty(),
)
fmt.Println(res, err)

const response = await client.search({
  query: {
    match_all: {},
  },
});
console.log(response);

GET /_search
{
    "query": {
        "match_all": {}
    }
}

The _score can be changed with the boost parameter:

resp = client.search(
    query={
        "match_all": {
            "boost": 1.2
        }
    },
)
print(resp)

response = client.search(
  body: {
    query: {
      match_all: {
        boost: 1.2
      }
    }
  }
)
puts response

res, err := es.Search(
    es.Search.WithBody(strings.NewReader(`{
      "query": {
        "match_all": {
          "boost": 1.2
        }
      }
    }`)),
    es.Search.WithPretty(),
)
fmt.Println(res, err)

const response = await client.search({
  query: {
    match_all: {
      boost: 1.2,
    },
  },
});
console.log(response);

GET /_search
{
  "query": {
    "match_all": { "boost" : 1.2 }
  }
}

Match None Query

This is the inverse of the match_all query, which matches no documents.

resp = client.search(
    query={
        "match_none": {}
    },
)
print(resp)

response = client.search(
  body: {
    query: {
      match_none: {}
    }
  }
)
puts response

res, err := es.Search(
    es.Search.WithBody(strings.NewReader(`{
      "query": {
        "match_none": {}
      }
    }`)),
    es.Search.WithPretty(),
)
fmt.Println(res, err)

const response = await client.search({
  query: {
    match_none: {},
  },
});
console.log(response);

GET /_search
{
  "query": {
    "match_none": {}
  }
}
