theoretically #24068 has better perf because it builds the `SearchArgument` only once, but seems it doesn't matter as the perf difference should be very small. Since @IvanVergiliev has spent a lot of effort on #24068 and the PR itself is corrected, how about we merge #24068 first and then send a followup PR to simplify it?
