Thanks, Paul. This is working well for me and I can happily use multiple 
SpanTermQueries embedded in a SpanOrQuery in place of each of the single 
words in your example.

SpanNotQuery(
	SpanOrQuery(interested,curious...) 
	SpanNearQuery(
		SpanOrQuery(not,wasnt,isnt,...)
		SpanOrQuery(interested,curious...)
		)
	)

I've never tried it myself, so it's good to hear that it actually works...

How about sth like this to get rid of the duplicates in there:

SpanNotNearQuery(includeSpanQuery, excludeSpanQuery, distance, ordered)

?
Writing the SpanScorer for that would be some work, though.
