A string to use as the separator when splitting the input string.

position: Int32

An integer zero-based position of the token to pick after the input string is split.

Returns

For example, if the input is Jane Doe, the delimiter is " " (space) and the position is 0, the result is Jane; if the position is 1, the result is Doe. If the position refers to a token that doesn't exist, an error will be returned.

Sample use case: Your data source contains a PersonName field, and you want to index it as two separate FirstName and LastName fields. You can use this function to split the input using the space character as the delimiter.
