# IndexOf

This Expression returns a number indicating the position of the first character of a string being searched for within the databox value or 0 (zero) if no string match is found.

The syntax of the expression is as follows - parameters:

1\. string - a list of strings that should be searched for within the databox value\
2\. string - the list delimiter e.g. a comma (",") to indicate how to split the string in the first parameter\
3\. integer - 1 to indicate that the string comparison should ignore case, 0 to indicate that the string comparison should take case into consideration (i.e. when 1 "LiKeS" = "likes"
