To limit a search to only valid dimension values within results
of dimension search, use the Dimension Search Scope parameter,
Dn.
The Dimension Search Scope parameter
(Dn) is useful in conjunction with the other dimension search
parameters to limit a search to only valid dimension values that can be
combined with a specified navigation request to form a valid refinement
request.
This is different from specifying a single dimension to search within. Think of this as a search within results for dimension search.
To search within a navigation state:
For example, in this configuration:
|
Dimension |
Dimension values |
|---|---|
|
|
|
|
|
|
|
|
|
if neither the
Red Rocks nor the
Red Hill winery dimension values are valid
refinements for the
Wine Types: Red Wine navigation query, then the
following query:
D=red&Dn=40
where the
Red Wine dimension value has an ID of
40, returns only the dimension
Wineries and the dimension values
Green & Red.
