Given the possibility of nested span queries, it might be best
do this is by reindexing the field to be highlighted in ram, reuse
the span query on it for collecting the Spans (via getSpans())
and use the beginnings and the ends from this spans as
the basis for highlighting.
For efficiency during reindexing the analyzer used to assemble
the lucene document could ignore all tokens that will not match,
except for their positions.
