Jack Krupansky commented on LUCENE-6305:
----------------------------------------
No objection, but it would be good for the javadoc for BQ and BQ.Builder to
explicitly state the contract that the order that clauses are added will not
impact either the results of the query, their order, or the performance of the
execution of the query - assuming those facts are all true.
> BooleanQuery.equals should ignore clause order

> BooleanQuery.equals is sensitive to the order in which clauses have been
> added. So for instance "+A +B" would be considered different from "+B +A"
> although it generates the same matches and scores.
