Hello, I want to know the usage of " * " symbol in $regex operator in " s " operation.
The “*” symbol means multiple times, check out this example on the mongodb documentation.
Didn’t quite understand the use case of " * " symbol in the documentation example, does that mean the word line is expected multiple times?? .Elaborate explanation is appreciated!
In the documentation example the “*” is repeating the “.” symbol multiple times, and “.” is wildcard for allowing and character.
So, the regex
/m.*line/ in the example will match the following strings.
“many trees are planted in line”
“monkeys can hang from a line”
