/**
 * where 仿orm操作  类似于mysql的查询组合  _id>2 and (_id=3 or _id=4)
 * 目前支持的操作符
 * =        等于
 * <        小于
 * <=       小于等于
 * >        大于
 * >=       大于等于
 * <>或!=   不等于 
 * in   in查询
 * nin  not in 查询
 * 
 * 展示指定字段
 * field(['email'=>1, 'name'=>1,'_id'=>0])
 * 1是展示 0是排除 
 * 要注意一下，用email=1, name=0是不行的，mongo官方会提示逻辑错误，除了_id可以自由设置0或1，其他字段要么全是1，要么全是0
 * 
 * 排序
 * sort($field, $desc)
 * $desc 1是升序，-1是降序  只能填1或者-1
