# MatchType

Fields with this property are optimized for whole value matching. Type `True` to store the associated PropertyFieldCSVs fields in a fast-look-up table in memory to optimize matching of the fields when using the following `FieldText` specifiers: `ARANGE`, `BIASVAL`, `EMPTY`, `EXISTS`, `EQUALCOVER`, `MATCH`, `MATCHALL`, `MATCHCOVER`, `NOTMATCH`, `NOTSTRING`, `NOTSTRING`, `STRING`, `STRINGALL`, and `WILD`.

NOTE: You cannot configure a field with more than one numeric-based field type concurrently. Numeric-based types include NumericType, NumericDateType, MatchType, ParametricRangeType, ReferenceMemoryMappedType, and ParametricType when the `ParametricNumericMapping` configuration parameter is set to `True`.
