Is it possible to conduct a feature search within a search in ArcGIS Online?
Yes. In some instances, users may want to conduct multiple levels of feature searches on a layer. For example, users may wish to search for restaurants and filter results to show only pizzerias.
ArcGIS Online offers three templates which can be configured to apply multiple layers of filters to the search results: the ‘Find, Edit and Filter’ template, the 'Filter’ template, and the ‘Finder’ template.
