• Searchable Class Occurrence {dmaProp_SearchableClassOccurrence}

This is the occurrence number of the searchable class in the current query.

In each query, the searchable class occurrences are assigned non negative integers by the client. These integers are unique in the context of the current query. This is necessary because the same searchable class can occur more than once in the From Expression’s of the query. References to properties in the query are tied to a particular searchable class occurrence.

• Property Id {dmaProp_PropertyId}

Specifies the property of the searchable class. The value may be any one of the identifiers for the desired property.
