Search Protocol Handler Error Messages

Error messages returned by protocol handlers:

Constant/value	Description
PRTH_E_ACCESS_DENIED 0x80041205L	Access was denied. If this occurs during an incremental crawl, the file is deleted from the gatherer's URL queue.
PRTH_E_ACL_IS_READ_NONE 0x80041211L	Item will not be indexed. Its ACL allows no one to read the item.
PRTH_E_ACL_TOO_BIG 0x80041212L	ACL exceeded 64 KB. Search does not index the item.
PRTH_E_BAD_REQUEST 0x80041208L	Request was invalid because of an error in the URL.
PRTH_E_COMM_ERROR 0x80041200L	Indicates a communication or server error. If there are too many of these errors for a particular server, the gatherer marks the server as unavailable.
PRTH_E_NOT_REDIRECTED 0x80041207L	Redirected URL does not exist.
PRTH_E_OBJ_NOT_FOUND 0x80041201L	Object not found. Indicates that the gatherer should delete the document from the queue if it is not found during an incremental crawl.
PRTH_E_REQUEST_ERROR 0x80041202L	Options used are not supported.
PRTH_E_SERVER_ERROR 0x80041206L	Communication or server error. If there are too many of these errors for a particular server, the gatherer marks the server as unavailable.
PRTH_S_NOT_ALL_PARTS 0x8004121BL	Parts of an item cannot be accessed.
PRTH_S_NOT_MODIFIED 0x00041203L	Item content has not changed. If this error occurs during an incremental crawl, the gatherer skips this item because the item has not changed.
PRTH_S_TRY_IMPERSONATING 0x00041225L	Item should be accessed while impersonating a user. The protocol handler is expected to implement IUrlAccessor3::GetImpersonationSidBlobs so that the search protocol host can retrieve a list of SIDs to use for impersonation and can revert to using IUrlAccessor2, impersonating one of the allowed users when opening the item.
