    Grammar

    FIND(find_text,within_text,start_num)

    Returns the first specified substring (find_text) in the character string (within_text) starting from the index position (start_num).

    iconNote:
    For real-time data, a defaulted value needs to be added if there are fewer than 3 parameters in the function.

    Parameter 1

    find_text

    A substring to be found

    Parameter 2

    within_text

    A string containing the substring to be found (find_text)

    The search starts from the first character of within_text. If start_num is not specified, the default value 1 is used.

    Parameter 3

    start_num

    Index position where the search starts.

    iconNote:
    Negative values are not supported in real-time data.


    iconNote:
    The function returns 0 if no find_text is found.

    Notes

    • The first and second parameters of the FIND function are of any type and the third is a number that can be defaulted.

    Example

    Take fuzzy search as an example, which is similar to the LIKE operator in SQL.

    Add a formula column to label values containing Women, Men, and other characters in Category description in the built-in Store sales statistics dataset as "Women Products", Men Products", and "Others", respectively.

    Enter the formula IF(FIND("Women",Category description)!=0,"Women Products",IF(FIND("Men",Category description)!=0,"Men Products","Others")), as shown in the following figure.

    iconNote:
    Only values of Category description fields displayed with a blue background are valid.

    The following table explains each part of the formula above.
