FieldRestriction

The names of fields that the query terms must occur in. IDOL Content Component applies this field restriction to any terms in the query text that do not already have an explicit field restriction. The action matches only documents that contain the query terms in one of the specified fields.

To specify that the fields in the FieldRestriction parameter are the only fields that the query can use in the matching process for both the Text and FieldText action parameters, set HardFieldRestriction to True.

In complex expressions, IDOL Content Component applies the FieldRestriction parameter after all other field restrictions in the expression. For example:

Text=frog+(fish+toad:AMPHIBIAN):VERTEBRATE&FieldRestriction=ANIMAL

is equivalent to the following expression:

Text=frog:ANIMAL+(fish:VERTEBRATE+toad:AMPHIBIAN)

In this example, if you also set HardFieldRestriction to True, the action returns results only for the frog:ANIMAL term and restriction.

Default:  
Example: FieldRestriction=CREATURE:FAUNA
In this example, if the query text is cat+dog:ANIMAL+rabbit, the specified FieldRestriction applies to the terms cat and rabbit, but not to the term dog (because it already has a field restriction). The query returns only documents that contain the value dog in an ANIMAL field, the value cat in a CREATURE or FAUNA field or the value rabbit in a CREATURE or FAUNA field.
