As described in the Standard Query Results section, ATG Search returns the information associated with the index item of each statement result. This information includes related item (document) sets of the index item. By default, ATG Search returns all related item sets, but the number and type of the returned item sets can be controlled by this attribute:
<structquery maxRelatedSets="max" relatedSets="path,path,..."
The max value is the maximum number of related sets to return. A value of 0 means no related item set information is returned in the response. The default is 1000. The path values are item set paths (for instance, /Topics/Product) which act as constraints on what type of related sets to return. Only related sets that are descendents of one of the path values are returned. The default value is an empty string, which means that the related sets are unconstrained.
