ATG Search results paging is controlled by the following attributes:
<similardocs pageNum="num" pageSize="size"
The pageSize attribute controls how many results are returned at one time. If pageSize is empty, no paging is performing. If paging is used, and the results do not fit on a single page, resubmit the query with pageNum="1", pageNum="2", etc. to access the additional results (the first result page is page 0).
ATG strongly recommends that you do not use a pageSize value greater than 100, as this can lead to performance problems or even Search engine failure.
