Set CaseSensitive to "False" when comparing and matching values regardless of character case.
For elements using DataLayer.ActiveSQL, CaseSensitive may be set to "DataSourceCollation". Then case sensitivity is defined by the database column's "collation" which may be sensitive or not. This option can provide better performance for case-insensitive filters.
For AnalysisFilter with DataLayer.ActiveSQL and SqlCompareFilter, the default is "DataSourceCollation". The default is "True" for all other elements.
