On any map, you can search for existing placemarks, lines or tracks. Tap the search icon (magnifying glass), and enter a term into the search box and a list of results will appear below it. This search function can use either the existing features on the map or Open Street Map to find what you are looking for (e.g. coffee shops). You can also use this search function from My Maps to look for a specific map in your maps list.
If no matches are returned or if you're searching for other points of interest, you can search OpenStreetMap.
