protected function IgnoreCharacters::process in Search API 8

Processes a single string value.

This method is ultimately called for all text by the standard implementation, and does nothing by default.

Parameters

mixed $value: The value to preprocess, as a reference. Can be manipulated directly, nothing has to be returned. Since this can be called for all value types, $value has to remain the same type. The possible types for $value depend on shouldProcess().
