categories, see
cfsearch in Chapter 2, “ColdFusion Tags,” in CFML Reference.
Retrieving information about the categories contained in a collection
You can retrieve the category information for a collection by using the
cfcollection tag’s
categoryList action. The categoryList action returns a structure that contains two keys:
You can use the information returned by
categoryList to display to users the number of
documents available for searching, as well the document tree available for searching. You can also
create a search interface that lets the user select what category to search within based on the results
returned by
categoryList.
