Adrien Grand commented on LUCENE-7497: -------------------------------------- This collector needs access to Scorer.getChildren() that BS1 does not expose. Fixing BS1 to expose sub scorers would be fairly costly, so we added a note to {{ToParentBlockJoinCollector}} to recommend using {{ToParentBlockJoinIndexSearcher}}, an IndexSearcher which disables bulk scoring: {code} * <p>This collector MUST be used with {@link ToParentBlockJoinIndexSearcher}, * in order to work correctly. {code} See also LUCENE-6959. > Cannot use boolean SHOULD queries with block join? > -------------------------------------------------- > > Key: LUCENE-7497 > URL: https://issues.apache.org/jira/browse/LUCENE-7497 > Project: Lucene - Core > Issue Type: Bug > Reporter: Michael McCandless > Attachments: LUCENE-7497.patch > > > I'm in the process of upgrading http://jirasearch.mikemccandless.com (based > on 4.10.x in production today!) to Lucene 6.x, but hit this tricky bug. > When I run the new test case, I hit this: > {noformat} > 1) testBQShouldJoinedChild(org.apache.lucene.search.join.TestBlockJoin) > java.lang.UnsupportedOperationException > at > __randomizedtesting.SeedInfo.seed([4D5C76211B3E41E1:48F4B8C556F02AB0]:0) > at org.apache.lucene.search.FakeScorer.getChildren(FakeScorer.java:60) > at > org.apache.lucene.search.join.ToParentBlockJoinCollector$1.setScorer(ToParentBlockJoinCollector.java:190) > at > org.apache.lucene.search.FilterLeafCollector.setScorer(FilterLeafCollector.java:38) > at > org.apache.lucene.search.AssertingLeafCollector.setScorer(AssertingLeafCollector.java:43) > at > org.apache.lucene.search.FilterLeafCollector.setScorer(FilterLeafCollector.java:38) > at > org.apache.lucene.search.AssertingLeafCollector.setScorer(AssertingLeafCollector.java:43) > at org.apache.lucene.search.BooleanScorer.score(BooleanScorer.java:319) > at org.apache.lucene.search.BulkScorer.score(BulkScorer.java:39) > at > org.apache.lucene.search.AssertingBulkScorer.score(AssertingBulkScorer.java:69) > at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:669) > at > org.apache.lucene.search.AssertingIndexSearcher.search(AssertingIndexSearcher.java:91) > at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:473) > at > org.apache.lucene.search.join.TestBlockJoin.testBQShouldJoinedChild(TestBlockJoin.java:233) > {noformat} > Not sure how to fix it ... it happens because jirasearch runs SHOULD queries > against the child docs (one child doc per jira comment) and parent docs text > fields (one child doc per jira issue). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
