Github user mattweber commented on the issue:

    https://github.com/apache/lucene-solr/pull/129
  
    @mikemccand I addressed you comments.  I also added some more tests and fixed a bug that
would yield wrong increment when a term that had previously been seen was found again with
an increment of 0.  Tests were added.  I have squashed these changes with the previous commit
so it is clear to see the difference between the original PR which did not support position
increments and the new one that does.

> With [LUCENE-6664|https://issues.apache.org/jira/browse/LUCENE-6664] we can use multi-term
synonyms query time.  A "graph token stream" will be created which which is nothing more than
using the position length attribute on stacked tokens to indicate how many positions a token
should span.  Currently the position length attribute on tokens is ignored during query parsing.
 This issue will add support for handling these graph token streams inside the QueryBuilder
utility class used by query parsers.
