> 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.
