> MultiSearcher is using:
> queries[i] = searchables[i].rewrite(original);
> to rewrite query and then use combine to combine them.
> But SpanRegexQuery's rewrite is different from others.
> After you call it on the same query, it always return the same rewritten queries.
> As a result, only search on the first IndexSearcher work. All others are using the first
IndexSearcher's rewrite queries.
> So many terms are missing and return unexpected result.
