rajanimaski commented on SOLR-14607: ------------------------------------ 1 and 4 actually works better. Saw a major issue when LTR tries to compute features on lengthy query string, 10-15 terms, it uses the heap fully and cause full GC stops solr response. For reference - https://issues.apache.org/jira/browse/SOLR-17018 > LTR Query, timeAllowed parameter causes a timeout exception with no result > -------------------------------------------------------------------------- > > Key: SOLR-14607 > URL: https://issues.apache.org/jira/browse/SOLR-14607 > Project: Solr > Issue Type: Improvement > Components: contrib - LTR > Affects Versions: 9.0 > Reporter: Shiming Li > Priority: Minor > Attachments: SOLR-14607-poc.patch > > Time Spent: 2h 10m > Remaining Estimate: 0h > > 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.

'LTRScoringQuery.CreateWeight' or 'LTRScoringQuery.createWeightsParallel'. > Here is the loading stage, timeout directly end is acceptable. > 2. 'ModelWeight.scorer'.
