interface ConditionSetInterface {

  /**
   * Adds a new ($field $operator $value) condition.
   *
   * @param string $field
   *   The ID of the field to filter on, for example "status". The special
   *   fields "search_api_datasource" (filter on datasource ID),
   *   "search_api_language" (filter on language code) and "search_api_id"
   *   (filter on item ID) can be used in addition to all indexed fields on the
   *   index.
   *   However, for filtering on language code, using
   *   \Drupal\search_api\Query\QueryInterface::setLanguages() is the preferred
   *   method, unless a complex condition containing the language code is
   *   required.
   * @param mixed $value
   *   The value the field should have (or be related to by the operator). If
   *   $operator is "IN" or "NOT IN", $value has to be an array of values. If
   *   $operator is "BETWEEN" or "NOT BETWEEN", it has to be an array with
   *   exactly two values: the lower bound in key 0 and the upper bound in key 1
   *   (both inclusive). Otherwise, $value must be a scalar.
   * @param string $operator
   *   The operator to use for checking the constraint. The following operators
   *   are always supported for primitive types: "=", "<>", "<", "<=", ">=",
   *   ">", "IN", "NOT IN", "BETWEEN", "NOT BETWEEN". They have the same
   *   semantics as the corresponding SQL operators. Other operators might be
   *   added by backend features.
   *   If $field is a fulltext field, $operator can only be "=" or "<>", which
   *   are in this case interpreted as "contains" or "doesn't contain",
   *   respectively.
   *   If $value is NULL, $operator also can only be "=" or "<>", meaning the
   *   field must have no or some value, respectively.
   *
   * @return $this
   */

  /**

   * @param \Drupal\search_api\Query\ConditionGroupInterface $condition_group
   *   A condition group that should be added.
