IndexManager :: MatchByType - Match objects by type
The function searches the objects from selected keywords by type passed in typenames. When no type name has been passed or when the type name is empty, the function returns all matching objects.
In order to increase performance, a maximum number of result instances can be passed to the function.
In contrast to SearchByType(), the function returns objects only, where all keywords (except stop words) match.
Return value: Number of items ( int32 )
The value contains the number of items (characters, entries, instances etc.).
