if you turn off html5mode the URL:
http://127.0.0.1/webroot/start.html?Venue=XXX
becomes
http://127.0.0.1/webroot/start.html#/?Venue=XXX
if you want use hashbang URL (for SEO, Facebook or whatever) you should add the "!" prefix to your URL, with:
$locationProvider.html5Mode(false).hashPrefix('!');
And your URL becomes:
http://127.0.0.1/webroot/start.html#!/?Venue=XXX
the search method of $location should work, following the documentation
Move from html5Mode to hashbang (or vice versa) needs you to refactor the links in your app. To avoid this kind of situation I prefer using ui-router and modify links in terms of state transition (i.e. using ui-sref). In this way, it's ui-router that modify the URL with or without the hash for you
