Hi Michael,
I haven't executed this yet, but can you try this:
SpanNotQuery(SpanNearQuery("George Washington"), SpanNearQuery("George Washington
Carver"))

I'm trying to solve the following problem...
I have 3 documents that contain the following contents:
1: "George Washington Carver blah blah blah."
2: "George Washington blah blah blah."
3: "George Washington Carver blah blah blah. George Washington blah blah blah."
I want to create a query that matches documents 2 and 3, but not 1. That is, I want to find documents that
mention "George Washington". It's okay if they also mention "George Washington Carver",
but I don't want documents that only mention "George Washington Carver". So simply doing something
like this does not solve it:
"George Washington" NOT "George Washington Carver"
Is there a Query type that does this out of the box? I've looked at the various
types of span queries, but none of them seem to do this. I think it should be
theoretically possible given the position data that Lucene stores...
