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.
You cannot configure a field with two numeric-based types concurrently. Numeric-based types include
ParametricType when the
ParametricNumericMapping configuration parameter is set to
Content converts dates to numerical values (epoch seconds) and identifies the fields that contain the numerical date values.
Open the IDOL Content component configuration file in a text editor.
List a process that identifies numeric date fields in the
[FieldProcessing] section. For example:
[FieldProcessing] 0=MyFirstProcess 1=NumericDateFields
Create a section for each process that you listed, and in each section, create a property for the process (you define the property by setting one or more applicable configuration parameters). Identify the fields that you want to associate with the process.
The properties that you create must not have the same name as the processes.
[MyFirstProcess] Property=MyProperty PropertyFieldCSVs=*/MyField,*/MyOtherField [NumericDateFields] Property=NumDate PropertyFieldCSVs=*/BIRTHDAY,*/STARTDATE
Create a section for the property in which you set the
NumericDateType parameter to
True. This enables Content to memory map the associated
PropertyFieldCSVs fields, and identify them as fields that contain date values. For example:
Save and close the configuration file.
Restart the IDOL Content component for your changes to take effect.
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.
BIRTHDAY field must contain a numeric date value that is between 01/01/1980 and 31/12/1980 for this document to be returned.
