A multi-feature query can run single-shot - one pass per (sub-query, table), with no meta query, no chunking and no key-range window - using a server-side cursor to keep memory bounded; an optional per-sub-query maximum bounds each sub-query. When paged, numberMatched is computed across all sub-queries (the invariant total) while value queries are executed only for the sub-queries needed for the page.
