> When the accord route index searches for range transactions we pass in a
> min/max timestamp range to search for, but this gets ignored. The issue with
> ignoring it is that we will do unneeded disk searches as we will include
> segments that don’t have data for the range and must get filtered out after
> the read.
> We should respect the txn_id passed in to limit the segments to only the ones
> that “could” match.
