DialogWeb Help:   Set Numbers

Each Dynamic Search creates a temporary group, or set, of records that includes your search terms. The sets are assigned sequential numbers, beginning with set S1. When you refine a search in Dynamic Search, a list of your current sets displays along with the Dynamic Search form. You can select a set and combine it with new data entered on the form. You can also combine sets in a search, for example, you can enter s1 and s2 in the Search for text box.
