> In positional queries, it's common to want to promote some terms over others;
> for example, in lists of synonyms you may want the original term to be
> weighted more, or more specific terms to receive higher weights than less
> specific ones.
> Span queries have the 'SpanBoostQuery', which is currently broken; and a
> 'PayloadScoreQuery' which allows direct modification of the score based on
> stored payloads, but which does not deal well with a mix of terms
> with-and-without payloads, and which ends up exposing a lot of the terms API,
> making it very difficult to customize.
> For interval queries, I'd like to try a different approach, adding a
> float-valued 'boost()' method to IntervalIterator. This would make it easy
> to add simple boosts around particular terms in terms lists, and also allow
> more fine-grained control using payloads without having to expose the
> mechanics of the PostingsEnum
