The filter allows you to configure filtering rules such as field sizes to filter data. Only data that meets the specified rules will be retained.
Notes
Filter matching is case-sensitive and accurate down to the character. During matching, no standardized operations will be performed on strings.
Values to be matched must be in JSON format, which include strings and numeric values enclosed in quotation marks as well as keywords not enclosed in quotation marks (
true, false, and null).Prefix Match
You can perform key value matching by comparing a specified prefix with the prefix in data.
For example, for data
{"password":"topicname"}, you can specify top as the prefix of the password value so that {"password":"topicname"} can be normally matched.Suffix Match
You can perform key value matching by comparing a specified suffix with the suffix in data.
For example, for data
{"password":"topicname"}, you can specify name as the suffix of the password value so that {"password":"topicname"} can be normally matched.Inclusion Match
You can specify a field to be included in data as a match condition.
For example, for data
{"password":"topicname"}, you can specify na to be included in the password value so that {"password":"topicname"} can be normally matched.Exclusion Match
You can specify a field to be excluded from data as a match condition.
For example, for data
{"password":"topicname"}, you can specify topicname to be excluded from the password value so that {"password":"topicname"} cannot be normally matched.Numeric Match
You can specify the value or value range of a certain field as a match condition.
For example, for data
{ "numeric": 10}, you can specify the value of numeric to be less than 15 (<15) as a match condition so that { "numeric": 10} can be normally matched.The following are examples of value match rules:
Greater than 10: Enter `>10`
Greater than or equal to 10: Enter `>=10`
Greater than or equal to 10, and less than or equal to 20: Enter `>=10&<=20`
Greater than or equal to 10, or less than or equal to 5: Enter `>=10|<=5`
IP Match
You can specify an IP in CIDR notation as a match condition. For example, you can enter
1.2.3.4/24 to match IPs whose leading 24 bits start with "1.2.3.".
