IRowsetPrioritization interface (searchapi.h)
Sets or retrieves the current indexer prioritization level for the scope specified by this query.
Inheritance
The IRowsetPrioritization interface inherits from the IUnknown interface. IRowsetPrioritization also has these types of members:
Methods
The IRowsetPrioritization interface has these methods.
| IRowsetPrioritization::GetScopePriority Retrieves the current indexer prioritization level for the scope specified by this query. |
| IRowsetPrioritization::GetScopeStatistics Gets information describing the scope specified by this query. |
| IRowsetPrioritization::SetScopePriority Sets the current indexer prioritization level for the scope specified by this query. |
Remarks
This interface is acquired with IUnknown::QueryInterface Method on an indexer rowset. DBPROP_ENABLEROWSETEVENTS must be set to TRUE with the OLE DB ICommandProperties::SetProperties method prior to executing the query in order to use rowset prioritization.
IRowsetPrioritization::SetScopePriority sets the prioritization for the scopes belonging to the query, and the interval the scope statistics event is raised when there are outstanding documents to be indexed within the query scopes. This event is raised if the priority level is set to default.
IRowsetPrioritization::GetScopeStatistics can be used to get the number of indexed items in the scope, the number of outstanding documents to be added in the scope, and the number of documents that need to be re-indexed within this scope.
For a sample that demonstrates how to prioritize indexing events, see the SearchEvents sample.
