You can configure the IDOL Content component to identify fields that contain numerical values. When these fields are indexed, Content stores them in a fast look-up table in memory, so that it can quickly return the field. A numeric field can contain a comma-separated list of numbers. Content stores each value as a numeric value for this field, for this document.
You cannot configure a field with two numeric-based types concurrently. Numeric-based types include
ParametricType when the
ParametricNumericMapping configuration parameter is set to
Open the IDOL Content component configuration file in a text editor.
List a process that identifies numeric fields in the
[FieldProcessing] section. For example:
[FieldProcessing] 0=MyFirstProcess 1=PriceFields
Create a section for each process that you listed, and in each section, declare a property for the process (you define the property later 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 [PriceFields] Property=Price PropertyFieldCSVs=*/PRICE
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
PRICE 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.
PRICE field must contain a number between 50 and 100 (including decimal numbers) for this document to return.
IDOL Server sorts the results that it returns for the query according to the values that their
PRICE fields contain. The results whose
PRICE field contains the smallest value is listed first, followed by results with increasing values in the
