- - **search** - search markers on map for name containing `string`. An empty string `""` clears the search results. - `{command:{search:"Dave"}}`
+ - **search** - search markers on map for name containing `string`. If not found in existing markers, will then try geocoding looking using Nominatim. An empty string `""` clears the search results. - `{command:{search:"Dave"}}`
  - **showlayer** - show the named overlay(s) - `{command:{showlayer:"foo"}}` or `{command:{showlayer:["foo","bar"]}}`
