> Currently, mahout uses Lucene's non-reusable analysis API.
> This means that per-"document", a lot of objects are recreated (e.g. every
> TokenStream in the analysis chain, every Attribute).
> This can create a lot of unnecessary overhead, particularly if "documents"
> are short.
> It looks like an easy win to use the reusable API (reusableTokenStream)
> instead.
