Méthode	Description
CountInstancesOfCharacters ( string inString, char character ) : int
DateTimeToUnixTimestamp ( System.DateTime dateTime ) : int
GetPrefix ( string query, int prefixLength ) : string	Extract the prefix from a query, returns the prefix of length prefixLength, or null if the query is not long enough to extract a prefix from
SigmoidFunction ( double x, double max, double k, double n ) : double	Implements a sigmoid function with the parameters: y = max · k n / (k n + x n) (Returns Y value). See: http://numberlinx.org/Sigmoid%20Curves.html for visual parameter tuning examples.
