NumericDateType Fields

You can configure the IDOL Content component to identify fields that contain dates. When these fields are indexed, Content 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.

Content 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, Content 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.
