IMPORTANT: This documentation is no longer updated. Refer to Elastic's version policy and the latest documentation.

Match all query

edit

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(body={"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({
  body: {
    query: {
      match_all: {}
    }
  }
})
console.log(response)
GET /_search
{
    "query": {
        "match_all": {}
    }
}

The _score can be changed with the boost parameter:

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

Match None Query

edit

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

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