/**
 * ActiveRecord is the base class for classes representing relational data in terms of objects.
 *
 * This class implements the ActiveRecord pattern for the fulltext search and data storage
 * [Elasticsearch](https://www.elastic.co/products/elasticsearch).
 *
 * For defining a record a subclass should at least implement the [[attributes()]] method
 * to define attributes.
 * IMPORTANT: The primary key (the `_id` attribute) MUST NOT be included in [[attributes()]].
 *
 * The following is an example model called `Customer`:
 *
 * ```php
 * class Customer extends \yii\elasticsearch\ActiveRecord
 * {
 *     public function attributes()
 *     {
 *         return ['name', 'address', 'registration_date'];
 *     }
 * }
 * ```
 *
 * You may override [[index()]] and [[type()]] to define the index and type this record represents.
 * Types are being deprecated, and it is recommended to have a single type per index. For more information
 * read about [removal of mapping types](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html).
 * For Elasticsearch 7 and later (as configured in [[Connection]], [[type()]] is ignored.
 *
 * @property mixed $_id The primary key of the record. Can only be written to for new records, otherwise read-only.
 * @property array|null $highlight A list of arrays with highlighted excerpts indexed by field names.
 * This property is read-only.
 * @property float $score Returns the score of this record when it was retrieved via a [[find()]] query.
 * This property is read-only.
 * @property array|null $explanation An explanation for each hit on how its score was computed.
 * This property is read-only.
 *

     * - `timeout` timeout waiting for a shard to become available.

     * - `consistency` the write consistency of the index/delete operation.

     *   has been loaded from the database. Yii will set the `version` parameter to the value stored in [[version]].

     *   Make sure the record has been fetched with a [[version]] before. This is only the case
     *   for records fetched via [[get()]] and [[mget()]] by default. For normal queries, the `_version` field has to be fetched explicitly.
     *
     * @return int|bool the number of rows deleted, or false if the deletion is unsuccessful for some reason.
     * Note that it is possible the number of rows deleted is 0, even though the deletion execution is successful.
