> When an empty RegexCompletionQuery is provided to ContextQuery, the following assertion
failure occurs:
> {code:java}
> java.lang.AssertionError: input should not end with the context separator
> at org.apache.lucene.search.suggest.document.ContextQuery$ContextCompletionWeight.setInnerWeight(ContextQuery.java:296)
> at org.apache.lucene.search.suggest.document.ContextQuery$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.testEmptyRegexQuery(TestContextQuery.java:193)
> {code}
> This is a bit of an edge case, but may be concerning since without assertions enabled,
you can go on to access IntsRef indices that are out of bounds.
> The attached patch provides a reproduction of the issue, as the test case TestContextQuery#testEmptyRegexQuery.
Note that 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#testEmptyRegexQuery). In
this case, there is no error, and all suggestions are returned.
