Available since version2.0

Query represents a query to the search API of elasticsearch.

Query provides a set of methods to facilitate the specification of different parameters of the query. These methods can be chained together.

By calling createCommand(), we can get a yii\elasticsearch\Command instance which can be further used to perform/execute the DB query against a database.

For example,

$query = new Query;
$query->storedFields('id, name')
    ->from('myindex', 'users')
    ->limit(10);
// build and execute the query
$command = $query->createCommand();
$rows = $command->search(); // this way you get the raw output of elasticsearch.

You would normally call $query->search() instead of creating a command as this method adds the indexBy() feature and also removes some inconsistencies from the response.

Query also provides some methods to easier get some parts of the result only:

  • one(): returns a single record populated with the first row of data.
  • all(): returns all records based on the query results.
  • count(): returns the number of records.
  • scalar(): returns the value of the first column in the first row of the query result.
  • column(): returns the value of the first column in the query result.
  • exists(): returns a value indicating whether the query result has data or not.

NOTE: elasticsearch limits the number of records returned to 10 records by default. If you expect to get more records you should specify limit explicitly.

List of options that will passed to commands created by this query.

See also yii\elasticsearch\Command::$options.

public array $options = []
$postFilter public property (available since version 2.0.5)

See also https://www.elastic.co/guide/en/elasticsearch/guide/current/_post_filter.html.

public string|array $postFilter = null
$query public property

The query part of this search query. This is an array or json string that follows the format of the elasticsearch Query DSL.

public array|string $query = null
$scriptFields public property

The scripted fields being retrieved from the documents. Example: `php $query->scriptFields = [

'value_times_two' => [
    'script' => "doc['my_field_name'].value * 2",
],
'value_times_factor' => [
    'script' => "doc['my_field_name'].value * factor",
    'params' => [

    ],
],

] `

Note: Field values are always returned as arrays even if they only have one value.

See also:

public array $scriptFields = null
$source public property

This option controls how the _source field is returned from the documents. For example, ['id', 'name'] means that only the id and name field should be returned from _source. If not set, it means retrieving the full _source field unless \yii\elasticsearch\fields are specified. Setting this option to false will disable return of the _source field, this means that only the primaryKey of a record will be available in the result.

See also:

public array $source = null
$stats public property

The fields being retrieved from the documents. For example, ['id', 'name']. If not set, this option will not be applied to the query and no fields will be returned. In this case the _source field will be returned by default which can be configured using source(). Setting this to an empty array will result in no fields being retrieved, which means that only the primaryKey of a record will be available in the result. > Note: Field values are always returned as arrays even if they only have one value.
