When overtime, an ExitingReaderException is thrown. In the process of scoreFeatures of LTRQuery, ExitingReaderException will occur in two stages.
 * scorer: Occurs when a term needs to be loaded to the LeafReaderContext when creating Weight. * score: The term needs to be loaded when some functions call getValue. For example, FloatPayloadValueSource. So it can be compatible with this ExitingReaderException, and partly return. At least it's better than empty. # Solution In scoreFeatures method, catch ExitingReaderException and return the currently loaded document. # Tests Simulation throws ExitingReaderException in the scorer process, and partially returns the loaded document.
