Remarks

Search will return an ICursor with all of the rows that satisfy the constraints specified by a query filter. If a null value is provided for the QueryFilter parameter, the cursor will contain all of the selection set's rows.

The Recycling parameter controls row object allocation behavior.

Recycling cursors rehydrate a single feature/row object on each fetch and can be used to optimize read-only access, for example, when drawing. It is illegal to maintain a reference on a feature/row object returned by a recycling cursor across multiple calls to NextRow on the cursor. Feature/Row objects returned by a recycling cursor should not be modified. Non-recycling cursors return a separate object on each fetch.

The features/rows returned by a non-recycling cursor may be modified and stored with polymorphic behavior. The geodatabase guarantees "unique instance semantics" on non-recycling feature/row objects fetched during an edit session. If the object to be retrieved by a call to search has already been instantiated and is being referenced by the calling application, then a reference to the existing row object is returned.
