> SynonymFilter has two limitations today:
>   * It cannot create positions, so eg dns -> domain name service
>     creates blatantly wrong highlights (SOLR-3390, LUCENE-4499 and
>     others).
>   * It cannot consume a graph, so e.g. if you try to apply synonyms
>     after Kuromoji tokenizer I'm not sure what will happen.
> I've thought about how to fix these issues but it's really quite
> difficult with the current PosInc/PosLen graph representation, so I'd
> like to explore an alternative approach.
