> As an alternative to returning snippets, this highlighter provides the (term) position
for query matches.  One usecase for this is to reconcile the term position from the Solr index
with 'word' coordinates provided by an OCR process.  In this way we are able to 'highlight'
an image, like a page from a book or an article from a newspaper, in the locations that match
the user's query.
> This is based on the FastVectorHighlighter and requires that termVectors, termOffsets
and termPositions be stored.
