> According to the javadocs (QueryIndex) minimum cost for index is 1. Currently
> ReferenceIndex returns this minimum value, when it can be used for the query.
> But even then cost for remaining indexes is still calculated. We could skip
> cost calculation of remaining indexes if we achieved the minimum cost already.
> It will speed up all queries which can leverage the reference Index.
> Example query:
> SELECT * FROM [nt:base] WHERE PROPERTY([rep:members], 'WeakReference') =
> '345bef9b-ffa1-3e09-85df-1e03cfa0fb37'
