> Our current suggester impls do prefix matching of the incoming text
> against all compiled suggestions, but in some cases it's useful to
> allow infix matching. E.g, Netflix does infix suggestions in their
> search box.
> I did a straightforward impl, just using a normal Lucene index, and
> using PostingsHighlighter to highlight matching tokens in the
> suggestions.
> I think this likely only works well when your suggestions have a
> strong prior ranking (weight input to build), eg Netflix knows
> the popularity of movies.
