Search in URL

[nerijus]

Is it possible to implement search in URL? Like this - http://maps.lt/map/default.aspx?lang=lt#q=Kurkli%C5%B3%20g
It is needed for browser add-on (examples - https://addons.mozilla.org/lt/firefox/user/12027025/ , https://chrome.google.com/webstore/detail/search-mapslt-context-men/hoghaphlpakldhojcanpcepdagghciel).
