> It can be useful to report intervals from one fields as if they came from
> another. For example, fast prefix searches can be implemented by indexing
> text into two fields, one with the full terms and one with edge-ngrams
> enabled; to do proximity searches against terms and prefixes, you could wrap
> a term query against the ngrammed field so that its intervals appear to come
> from the normal field, and use it an an ordered or unordered interval.
> This is analogous to the FieldMaskingSpanQuery, but has the advantage that we
> don't use term statistics for scoring interval queries, so there is no issue
> with mixing up field weights from different fields.
