void ixEndRetrievalSession( OnixIndexManagerT IndexManager, StatusCodeT *Status)
IndexManager: The index manager which was obtained by the call to ixCreateIndexManager and associated with an index by a call to ixOpenIndex and has had an indexing session started by a call to ixStartIndexingSession.
Status: A pointer to a value of type StatusCodeT representing any error conditions.
If an error occurred, Status will be set to the error number.
ixEndRetrievalSession unloads an index from memory and should always be called before ixCloseIndex if a retrieval session has been started by a call to ixStartRetrievalSession. After this function call has been made, the index is not searchable until a subsequent call to ixStartRetrievalSession has been made.
