Mapit uses the OpenStreetMap address search by default, but your JIRA administrator can set one of the other search engines as default.
If your search matches more than one address, Mapit will list up to 30 matching results, ordered by distance to the current map center. If the search didn't return the result you expected, please try a more specific search.
OpenStreetMap is an open, free to use, community driven service, which means that it depends on local contributors to keep the maps up-to-date. If the map isn't quite up to date in your area, please consider contributing!
