Explorer is designed to make it easy to find the information you want, whether that is through the search dialog, or by clicking on a feature in the map.
To search, you can enter a search phrase directly into the search box and click Enter. By default, the search is set to search across all entities which have been configured in your app. If you would like to search for a specific entity or address, use the dropdown to focus your search on exactly what you're looking for. After you click Enter, a list of matching search results will be displayed. You can click on any of the results to view it in Explorer, or if there are many results you can expand the results and scroll through the list until you find what you were looking for.
Anther way to find what you want is by using the map to Identify things. In the Map Panel you can use the fixed zoom buttons, your mouse scroll wheel and cursor, or pinch zoom and pan (if you are on a touch enabled device) to change the map focus. If enabled, you can also use your device location by clicking on the location button and the map will adjust to your device location.
To identify a map item, click or tap it, and click the Info icon to see its Details.
