 ## Filtering Keys
 RedisShake supports filtering by key name, key name prefixes, and suffixes. You can set the following options in the configuration file, for example:
 ```toml
+[filter]
 allow_keys = ["user:1001", "product:2001"] # allowed key names  
 allow_key_prefix = ["user:", "product:"] # allowed key name prefixes
 allow_key_suffix = [":active", ":valid"] # allowed key name suffixes
+allow_key_regex = [":\\d{11}:"] # allowed key name regex, 11-digit mobile phone number
 block_keys = ["temp:1001", "cache:2001"] # blocked key names
 block_key_prefix = ["temp:", "cache:"] # blocked key name prefixes
 block_key_suffix = [":tmp", ":old"] # blocked key name suffixes
+block_key_regex = [":test:\\d{11}:"] # blocked key name regex, 11-digit mobile phone number with "test" prefix
 ```
 If these options are not set, all keys are allowed by default.
 
 ## Filtering Databases
 You can specify allowed or blocked database numbers, for example:
 ```toml
+[filter]
 allow_db = [0, 1, 2]
 block_db = [3, 4, 5]

 ## 过滤 Key
 RedisShake 支持通过键名、键名前缀和后缀进行过滤。您可以在配置文件中设置以下选项，例如：
 ```toml
+[filter]
 allow_keys = ["user:1001", "product:2001"] # 允许的键名
 allow_key_prefix = ["user:", "product:"] # 允许的键名前缀
 allow_key_suffix = [":active", ":valid"] # 允许的键名后缀
+allow_key_regex = [":\\d{11}:"] # 允许的键名正则，11位手机号
 block_keys = ["temp:1001", "cache:2001"] # 阻止的键名
 block_key_prefix = ["temp:", "cache:"] # 阻止的键名前缀
 block_key_suffix = [":tmp", ":old"] # 阻止的键名后缀
+block_key_regex = [":test:\\d{11}:"] # 阻止的键名正则，11位手机号，前缀为test
 ```
 如果不设置这些选项，默认允许所有键。

 ```toml
+[filter]
