> PostingsHighlighter uses the offsets encoded in the postings lists for the
> terms to find query matches.
> As such, it isn't really suitable for stuff like wildcards for two reasons:
> 1. an expensive rewrite against the term dictionary (i think other
> highlighters share this problem)
> 2. accumulating data from potentially many terms (e.g. reading many postings)
> However, we could provide an option for some of these queries to work, but in
> a different way, that avoids these downsides.
> Instead we can just grab the Automaton representation of the queries, and
> match it against the content directly (which won't blow up).
