Hello im trying to query the events portion of the calendar
ex.

luna-send -n 1 -a com.palm.calendar luna://com.palm.db/find '{"query": {"from": "com.palm.calendarevent:1", "where":[{"prop":"dtstart","op":"=", "val":"1280257200000"}]}}'

I have tried different fields but i keep getting:
{"errorCode":-3965,"errorText":"db: no index for query","returnValue":false}

Im i doing something wrong? how do you find out what fields are query-able?

Thanks
