> 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.
