hello everyone,

I'm so confused , in traditional way , i just post  parameters to server(eg
php java ), the server will accept and  handle it, but in couchdb , i just
can pass the "key", "startkey"..............?

my couchdb data as follows, its some geo infomation
{
    {"id": "101", "latitude": 50, "longitude": 100},
    {"id": "102", "latitude": 60, "longitude": 110},
    {"id": "103", "latitude": 70, "longitude": 80},
    {"id": "104", "latitude": 40, "longitude": 90},
    ..............................................................
    ..............................................................
    ..............................................................
{



I want to pass some parameters eg: my currentlocation["mylatitude": 100,
"mylongitude": 60],  radius  = 100(km) into couchdb, then i want to get the
data records whos location is in a  circle(radius 100)  around my
currentlocation

there is a fuction can get the distance between two location, thempt that
distance = getLoation(lat1, lon1, lat2, lon2), if i couchdb can get my
parameter, then i can use

if( getLoation(mylatitude, mylongitude, data[i].latitude, data[i].lonitude)
< radius)
{
    result.push(data);
}
return result;
...
what should i do, please give me a hand~~
