When I want to search by street/country/town don't work !
I find a bug in the source code
component->models->hotspot
line 178 to line 180
$street = $q->quoteName('m.name');
$country = $q->quoteName('m.name');
$town = $q->quoteName('m.name');

Should be modified to：
$street = $q->quoteName('m.street');
$country = $q->quoteName('m.country');
$town = $q->quoteName('m.town ');

then search by street/country/town work!
