QueryValidationOptions.skipUnknownFilters

Логический параметр, указывающий, следует ли пропускать неизвестные фильтры.

Если true, неизвестные фильтры пропускаются. Если false и validateFilters является true, неизвестные фильтры будут генерировать ошибки, если не будет предоставлен обработчик по умолчанию с QueryEngine.SetDefaultFilter.
