> ----------------------
>
> Key: LUCENE-7931
> URL: https://issues.apache.org/jira/browse/LUCENE-7931
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/search
> Affects Versions: 5.3.1
> Reporter: jin jing
>
> i find when use SpanNotQuery and the exclud key word like "not" "or" will
> give a error result
> example：
> doc1：the quick brown fox jumps over the lazy dog
> doc2：the quick red fox jumps over the sleepy cat
> doc3：the quick brown fox jumps over the lazy NOT dog
> String queryStringStart = "dog";
> String queryStringEnd = "quick";
> String excludeString = "NOT";
> SpanQuery queryStart = new SpanTermQuery(new Term("text",queryStringStart));
> SpanQuery queryEnd = new SpanTermQuery(new Term("text",queryStringEnd));
> SpanQuery excludeQuery = new SpanTermQuery(new Term("text",excludeString));
> SpanQuery spanNearQuery = new SpanNearQuery(
> new SpanQuery[] {queryStart,queryEnd}, 7, false, false);
>
> SpanNotQuery spanNotQuery = new SpanNotQuery(spanNearQuery, excludeQuery,
> 4,3);
> then this will return doc1 and doc3. so i think it is a bug.
