Description
Overview description:
I'm using the span query classes in Lucene to generate higher scores for
search results where the search terms are closer together. In certain
situations I want to exclude terms from the span. When I attempt to exclude
more than one term I get an error.
The example query I'm using is:
'brighton AND tourism' -pier -contents
I construct the query objects and the toString() version is:
spanNot(spanNear([contents:brighton contents:tourism], 10, false),
spanOr([contents:pier, contents:road]))
Steps to reproduce:
1. Construct a SpanNearQuery (must have at least one term, but at least two
makes more sense)
2. Construct a SpanOrQuery containing two or more terms
3. Construct a SpanNotQuery to include the first query object and exclude the
second (SpanOrQuery)
4. Execute the search
Actual Results:
A null pointer exception is thrown while generating the scores within the
search.
Stack trace:
java.lang.NullPointerException

Expected Resuts:
It executes the search and results where the first search terms (near query)
are close together but without the second terms (or query) appearing.
