Keep in mind that it may not scale real well. That -L feature was
kind of a hack -- I added it because we have the pre-sorted property
tables. There's no true index that is used to implement -L.
-L works by taking the presorted table (which is sizeof(int) * total
number of records in the index), sorting it by property then uses a
binary search to flag all the records in the range, and then sorts the
entire array again back in record number order and then uses that as a
lookup table for filtering the results.
