----------------------------------
Summary: FuzzyQuery should require positive maxExpansions
Key: LUCENE-5869
URL: https://issues.apache.org/jira/browse/LUCENE-5869
Project: Lucene - Core
Issue Type: Bug
Reporter: Ryan Ernst
FuzzyQuery currently only disallows negative values of {{maxExpansions}}.
However, passing {{0}} causes an NPE when the underlying {{TopTermsRewrite}}
does a {{peek()}} on an empty queue, which returns {{null}}, and then goes on
using it unknowingly.
