Intuitive API - Find

collection.find(query).skip(1000).limit(100);

collection.filter(query).skip(1000).limit(100).all();

Intuitive API - Remove

collection.remove(query);

collection.filter(query).remove();

Intuitive API - Find and Modify

collection.findAndModify(query, update);

collection.findAndModify(query, update, sort, false, update, true, false);

collection.filter(query) .sort(sort) .modifyAndGet(update, Get.AfterChangeApplied);
