Method NextSeekTerm

On the first call to Next() or if Accept(BytesRef) returns YES_AND_SEEK or NO_AND_SEEK, this method will be called to eventually seek the underlying TermsEnum to a new position. On the first call, currentTerm will be null, later calls will provide the term the underlying enum is positioned at. This method returns per default only one time the initial seek term and then null, so no repositioning is ever done.

Override this method, if you want a more sophisticated TermsEnum, that repositions the iterator during enumeration. If this method always returns null the enum is empty.

Please note: this method should always provide a greater term than the last enumerated term, else the behavior of this enum violates the contract for TermsEnums.
