Remarks

The Search method returns a search cursor that can be used to retrieve rows specified by a query filter. The recycling parameter controls row object allocation behavior. Recycling cursors rehydrate a single 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 row object returned by a recycling cursor across multiple calls to NextRow on the cursor.

Row objects returned by a recycling cursor should not be modified. Non-recycling cursors return a separate row object on each fetch. The objects returned by a non-recycling cursor may be modified and stored with polymorphic behavior. The geodatabase guarantees �unique instance semantics� on non-recycling row objects fetched during an edit session. If the row 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.

Non-recycling feature cursors returned from the Search method *MUST* be used when copying features from the cursor into an insert cursor of another class.  This is because a recycling cursor reuses the same geometry and under some circumstances all of the features inserted into the insert cursor may have the same geometry.  Using a non-recycling cursor ensures that each geometry is unique.

When using cursors within an edit session, they should always be scoped to edit operations. In other words, a cursor should be created after an edit operation has begun and should not be used once that edit operation has been stopped or aborted.
