   * Add a condition to the query or a condition group.
   *
   * For example, to find all entities containing both the Turkish 'merhaba'
   * and the Polish 'siema' within a 'greetings' text field:
   * @code
   *   $entity_ids = \Drupal::entityQuery($entity_type)
   *     ->condition('greetings', 'merhaba', '=', 'tr')
   *     ->condition('greetings.value', 'siema', '=', 'pl')
   *     ->execute();
   * @endcode
   *
   * @param $field
   *   Name of the field being queried. It must contain a field name, optionally
   *   followed by a column name. The column can be the reference property,
   *   usually "entity", for reference fields and that can be followed
   *   similarly by a field name and so on. Additionally, the target entity type
   *   can be specified by appending the ":target_entity_type_id" to "entity".
   *   Some examples:
   *   - nid
   *   - tags.value
   *   - tags
   *   - tags.entity.name
   *   - tags.entity:taxonomy_term.name
   *   - uid.entity.name
   *   - uid.entity:user.name
   *   "tags" "is the same as "tags.value" as value is the default column.
   *   If two or more conditions have the same field names they apply to the
   *   same delta within that field. In order to limit the condition to a
   *   specific item a numeric delta should be added between the field name and
   *   the column name.
   * @code
   *   ->condition('tags.5.value', 'news')
   * @endcode
   *   This will require condition to be satisfied on a specific delta of the
   *   field. The condition above will require the 6th value of the field to
   *   match the provided value. Further, it's possible to create a condition on
   *   the delta itself by using '%delta'. For example,
   * @code
   *   ->condition('tags.%delta', 5)
   * @endcode
   *   will find only entities which have at least six tags. Finally, the
   *   condition on the delta itself accompanied with a condition on the value
   *   will require the value to appear in the specific delta range. For
   *   example,
   * @code
   *   ->condition('tags.%delta', 0, '>'))
   *   ->condition('tags.%delta.value', 'news'))
   * @endcode
   *   will only find the "news" tag if it is not the first value. It should be
   *   noted that conditions on specific deltas and delta ranges are only
   *   supported when querying content entities.
   * @param $value
   *   The value for $field. In most cases, this is a scalar and it's treated as
   *   case-insensitive. For more complex operators, it is an array. The meaning
   *   of each element in the array is dependent on $operator.
   * @param $operator
   *   Possible values:
   *   - '=', '<>', '>', '>=', '<', '<=', 'STARTS_WITH', 'CONTAINS',
   *     'ENDS_WITH': These operators expect $value to be a literal of the
   *     same type as the column.
   *   - 'IN', 'NOT IN': These operators expect $value to be an array of
   *     literals of the same type as the column.
   *   - 'BETWEEN': This operator expects $value to be an array of two literals
   *     of the same type as the column.
   * @param $langcode
   *   Language code (optional). If omitted, any translation satisfies the
   *   condition. However, if two or more conditions omit the langcode within
   *   one condition group then they are presumed to apply to the same
   *   translation. If within one condition group one condition has a langcode
   *   and another does not they are not presumed to apply to the same
   *   translation.
