Based on a string value, searches a map service exposed by the ArcGIS Server REST API (available in ArcGIS Server 9.3 and above). The search can be conducted on a single field of a single layer, on many fields of a layer, or on many fields of many layers.

Set the URL to the ArcGIS Server REST resource that represents a map service, for example, http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer. For more information on constructing a URL, see Using the ArcGIS Services Directory.
