In this example, three strata are defined (strata 2, strata 1, and strata -1):
Nrcs=2,3001;2,3002;1,4001;1,4002;1,4003;-1,5001;-1,5002
When the query is processed, the dimension values are returned in this order:
Dimension values 3001 and 3002 are boosted above all others (i.e., are in the highest-ranked stratum).
Dimension values 4001 and 4002 are returned next (i.e., are in the second-ranked stratum).
All non-assigned dimension values are returned as part of stratum 0 (i.e., are in the third-ranked stratum).
Finally, dimension values 5001 and 5002 are buried (i.e., are in the lowest-ranked stratum).
This example shows how you can construct a hierarchy for the returned dimension values, and control the strata in which they are placed.
