#### Поддержка для функций {#podderzhka-dlia-funktsii}
#### Поддержка для функций {#functions-support}
Условия в секции `WHERE` содержат вызовы функций, оперирующих со столбцами. Если столбец - часть индекса, ClickHouse пытается использовать индекс при выполнении функции. Для разных видов индексов, ClickHouse поддерживает различные наборы функций, которые могут использоваться индексами.
Индекс `set` используется со всеми функциями. Наборы функций для остальных индексов представлены в таблице ниже.

Функции с постоянным агрументом, который меньше, чем размер ngram не могут использовать индекс `ngrambf_v1` для оптимизации запроса.
