Another use of categorization rules is to provide feedback to the end-user about the most relevant categories to the current query, allowing the end-user to manually refine (or narrow) the search. This categorization feedback is controlled by the following attribute:

<structquery suggestcat="max" suggestcatPrune="prune"
<structquery suggestcat="maxp"

The max value is the maximum number of categories to return in the feedback. If the max value is appended with a p or the suggestCatPrune value is true, then the optional taxonomy pruning post-processing algorithm is used during categorization, as described in the Categorization Process section of the Query Concepts and Processes chapter.
