> 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.
