Building a query.

query.js

var query1 = new Kinvey.Query();
query1.on('_geoloc').nearSphere([-97, 30], 100);// max 100 miles from Austin?

var query2 = new Kinvey.Query();
query2.on('_geoloc').nearSphere([-71, 42], 100);// max 100 miles from Boston?

var query3 = new Kinvey.Query();
query3.on('population').greaterThan(500000);// large city?

// Join all queries, result is saved in query1.
query1.or(query2).and(query3);// OR first, because of operator precedence.
