Use of "+" and "-" in queries

[Bill Tschumy]

I don't understand the difference in using + and - in queries compared 
to using AND and NOT.  Even the Query Syntax document seems a bit 
confused.  In the section on the NOT operator it says:

> To search for documents that contain "jakarta apache" but not 
"jakarta lucene" use the query:
>
> 
 "jakarta apache" NOT "jakarta lucene"
>
Then in the section on the - operator you read this:
> To search for documents that contain "jakarta apache" but not 
"jakarta lucene" use the query:
>
> 
 "jakarta apache" -"jakarta lucene"
>
So what's the difference?
