Oracle ATG Web Commerce Search applies rules to determine what categories of a taxonomy are relevant to the user queries. This allows the end-user to manually refine the search. This categorization feedback is controlled by the following attribute:

<query suggestcat="max" suggestcatPrune="prune"

<query 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.
