What if you were to make your field a multi-valued field, and at indexing time,
split up the text into sentences, putting each sentence into the solr document
as one of the values for the mv field? Then I think the normal highlighting
code can be used to pull the entire value (i.e. sentence) of a matching mv
instance within your document? I.E. put the 'overhead' into the index step,
rather than trying to do it at search time?
