Jim Ferenczi updated LUCENE-8288: --------------------------------- Attachment: LUCENE-8288.patch > ContextQuery "." for RegexCompletionQuery produces an assertion failure > ----------------------------------------------------------------------- > > Key: LUCENE-8288 > URL: https://issues.apache.org/jira/browse/LUCENE-8288 > Project: Lucene - Core > Issue Type: Bug > Reporter: Julie Tibshirani > Priority: Major > Attachments: LUCENE-8288-repro.patch, LUCENE-8288.patch > > > When a RegexCompletionQuery of "." is provided to ContextQuery, the following > assertion failure occurs: > {code:java} > java.lang.AssertionError: input should not end with a context separator > followed by SEP_LABEL > at > org.apache.lucene.search.suggest.document.ContextQuery$ContextCompletionWeight.setInnerWeight(ContextQuery.java:299) > at > org.apache.lucene.search.suggest.document.ContextQuery$ContextCompletionWeight.setNextMatch(ContextQuery.java:275) > at > org.apache.lucene.search.suggest.document.NRTSuggester.lookup(NRTSuggester.java:221) > at > org.apache.lucene.search.suggest.document.CompletionScorer.score(CompletionScorer.java:70) > at org.apache.lucene.search.BulkScorer.score(BulkScorer.java:39) > at > org.apache.lucene.search.suggest.document.SuggestIndexSearcher.suggest(SuggestIndexSearcher.java:78) > at > org.apache.lucene.search.suggest.document.SuggestIndexSearcher.suggest(SuggestIndexSearcher.java:58) > at > org.apache.lucene.search.suggest.document.TestContextQuery.testDotRegexQuery(TestContextQuery.java:188) > {code} > Note that this is a related, but distinct issue from > https://issues.apache.org/jira/browse/LUCENE-8287, where the > RegexCompletionQuery is empty. > The attached patch provides a reproduction of the issue, as the test case > TestContextQuery#testRegexDotQuery. To reproduce, Java assertions must be > enabled (as in the default configuration for tests). > The patch also provides a test case for the normal behavior of an empty > RegexCompletionQuery, when it is not wrapped in ContextQuery > (TestRegexCompletionQuery#testRegexDotQuery). In this case, there is no > error, and all suggestions are returned. > From a quick look, it seems as though "." doesn't capture any characters past > CompletionAnalyzer.SEP_LABEL, so the matching prefix in > ContextCompletionWeight#setInnerWeight is unexpectedly empty. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
