> The current equals and hashCode methods only compare query terms. This
> meant that queries on different fields, or with different field weights, are
> considered equal.
> During boolean query rewrites, duplicate clauses are removed. So because equals/
> hashCode is incorrect, rewrites can accidentally drop CombinedFieldQuery clauses.
