NumericDateType Fields

You can configure HPE IDOL Server to identify fields that contain dates. When these fields are indexed, HPE IDOL Server stores them in a fast look-up table in memory, so that it can quickly return the fields.

NOTE:

You cannot configure a field with two numeric-based types concurrently. Numeric-based types include NumericType, NumericDateType, MatchType, ParametricRangeType, ReferenceMemoryMappedType, and ParametricType when the ParametricNumericMapping configuration parameter is set to True.

HPE IDOL Server converts dates to numerical values (epoch seconds) and identifies the fields that contain the numerical date values.

If you now send a query for a specific value that is stored in the BIRTHDAY field, HPE IDOL Server memory maps the range that this value is in, so that it can return results more quickly next time a value that lies in this range is queried.

For example:

http://12.3.4.56:4000/action=Query&FieldText=RANGE{01/01/1980,31/12/1980}:BIRTHDAY

The BIRTHDAY field must contain a numeric date value that is between 01/01/1980 and 31/12/1980 for this document to be returned.
