Operators are ways of comparing data, used primarily in Filters, both hidden and visible.

This article goes into detail about the use of the 'Operators' field in Frontly and the different options available:
Equals
Compare 2 values to ensure they are identical
Does Not Equal
Compare 2 values to ensure they are not the same
Greater Than
Ensure a value is greater than another value, numerically
Less Than
Ensure a value is less than another value, numerically
Contains
Ensure that a value contains another value
Examples: A filter for "John Smith" contains "John" would be true because the entire "John" value exists within "John Smith".
A filter for "John Smith" contains "John Doe" would be false, because the entire "John Doe" value does not exist within "John Smith".
Does Not Contain
Ensure that a value does not contain another value. Same as the 'Contains' example above, but opposite.
Length Greater Than
Ensure a value's text length is greater than a certain number of characters
Length Less Than
Ensure a value's text length is less than a certain number of characters
Date After
For comparing 2 dates to ensure one is after the other
Date Before
For comparing 2 dates to ensure one is before the other
Exists
Ensure a value is valid or not empty
Does Not Exist
Ensure that a value is completely empty or not set
Advanced Operators
The following operators offer a more advanced and nuanced way of setting up your conditions around Frontly. These utilize terms that are familiar to developers so it's best to define what they mean first.
String: A sequence of characters (letters, numbers, symbols) treated as a single data type. For example, "hello" or "123abc" are strings.
Array: A collection of elements, typically of the same data type, stored in a specific order. Each element in an array can be accessed by its index (position). For example, ["apple", "banana", "cherry"] is an array of strings.
With these terms in mind, here are the advanced options:
String Equals String
Checks if two strings are exactly the same
Array Contains String
Checks if a string is an element within an array
String Contains String
Checks if one string is a substring of another string
String In Array
Same as "Array Contains String"; checks if a string is found within an array
String in String
Same as "String Contains String"; checks if one string is inside another string
String Not In String
Checks if one string is not a substring of another string
String Not In Array
Checks if a string is not an element within an array
Array Does Not Contain String
Same as "String Not In Array"; checks if a string is not present in an array
String Does Not Contain String
Same as "String Not In String"; checks if one string does not contain another string.
