Associate with each passStyle a RankCover that may be an overestimate,
and whose results therefore need to be filtered down. For example, because
there is not a smallest or biggest bigint, bound it by NaN (the last place
number) and '' (the empty string, which is the first place string). Thus,
a range query using this range may include these values, which would then
need to be filtered out.
