减少 或 去除 | "key-":Object,与"key+"相反 | "balance-":100.00,对应SQL是`balance = balance - 100.00`,余额减少100.00,即花费了100元

逻辑运算 | &, \|, ! 逻辑运算符 <br /><br />① & 可用于"key&{}":"条件"等<br /><br />② \| 可用于"key\|{}":"条件", "key\|{}":[]等,一般可省略<br /><br />③ ! 可单独使用,如"key!":Object,也可像&,\|一样配合其他功能符使用 | ① ["id&{}":">80000,<=90000"](http://apijson.cn:8080/head/{"User":{"id&{}":">80000,<=90000"}}),对应SQL是`id>80000 AND id<=90000`,即id满足id>80000 & id<=90000<br /><br /> ② ["id\|{}":">90000,<=80000"](http://apijson.cn:8080/head/{"User":{"id\|{}":">90000,<=80000"}}),同"id{}":">90000,<=80000",对应SQL是`id>80000 OR id<=90000`,即id满足id>90000 \| id<=80000<br /><br /> ③ ["id!{}":[82001,38710]](http://apijson.cn:8080/head/{"User":{"id!{}":[82001,38710]}}),对应SQL是`id NOT IN(82001,38710)`,即id满足 ! (id=82001 \| id=38710),可过滤黑名单的消息
