less { hop { filter_eq { all_rows ; model ; nd4 } ; top speed ( in operation ) （ km / h ） } ; hop { filter_eq { all_rows ; model ; nd5 } ; top speed ( in operation ) （ km / h ） } } = true
select the rows whose model record fuzzily matches to nd4 . take the top speed  in operation  （ km  h ） record of this row . select the rows whose model record fuzzily matches to nd5 . take the top speed  in operation  （ km  h ） record of this row . the first record is less than the second record .
