すべてにマッチ（Match all）

すべてのクエリに一致

最も単純なクエリで、すべてのドキュメントに一致し、すべてに _score の 1.0 を与えます。

Php

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

Python

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

Ruby

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

Go

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

Js

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

Console

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

_score は boost パラメータで変更できます:

Python

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

Ruby

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

Go

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

Js

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

Console

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

一致しないクエリ

これは match_all クエリの逆で、ドキュメントに一致しません。

Python

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

Ruby

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

Go

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

Js

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

Console

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