In contrast,
BrowseNodeLookup
only returns child browse nodes that are the direct descendant of the
browse node in the request. You could use any of the browse node IDs to either find additional, related
browse nodes by using another
BrowseNodeLookup
request, or to focus an
ItemSearch
request.
Use
ItemSearch
and
ItemLookup
and specify the BrowseNodes response group.
Find a browse node ID that is similar to the one you want and use
BrowseNodeLookup
to investigate its
child and ancestor browse nodes.

One of the reasons that customers enjoy shopping on Amazon is that Amazon has hundreds of thousands

makes requests more targeted and reduces search times. For example, when looking for a specific book,
it is best to specify the Books search index in the request.

Titles and keywords used to find items often occur in multiple search indices. For example, if you were

Books, DVD, Video, and Music.By specifying the search index you are interested in, your request becomes
much better targeted.
Specifying the wrong search index leads to no results or results that do not meet the customer's search
criteria. For example, if your keyword was carburetor and the search index was Kitchen, you might not
