You can do that today with Search::Tools::HiLiter, by concatenating the
doc field values into a temporary string. Search::Tools isn't as fast as
KS's Highlighter because it doesn't know in advance the positions and
offsets of the matching term, but the tokenizing and heat map algorithms
are similar (since I stole them from KS...).
