Description

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.
