> When using the LTR, open timeAllowed parameter, LTR feature of query may call 'ExitableFilterAtomicReader.CheckAndThrow' timeout checks.
> If a timeout occurs at this point, the exception ExitingReaderException is thrown, Lead to null result.
> Exception information:
> {code:java}
>  The request took too long to iterate over terms. Timeout: timeoutAt: 50321611131050 (System.nanoTime(): 50321639573838), TermsEnum=org.apache.lucene.codecs.blocktree.SegmentTermsEnum@62eaeeaa
> {code}
>  
> Can hold this exception in the LTR, returning partial results rather than null.
> This exception occurs in two places:
> 1. 'LTRScoringQuery.CreateWeight' or 'LTRScoringQuery.createWeightsParallel'. Here is the loading stage, timeout directly end is acceptable.
> 2. 'ModelWeight.scorer'. This is a stage that evaluates each Doc and can catch the exception, returns the computed document.
