AGSFindTask Class Reference

Description

This task performs text-based searches on an ArcGIS Server map service. The search is performed on only layers in the map service. Any tables in the map service are not searched. The search can be conducted on a single field of a single layer in the map service, on many fields of a layer, or on many fields of many layers.

A find task needs a URL to a REST resource that represents a Map service. For example, http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/SanFrancisco/311Incidents/MapServer
