Search
Searches for the position of specific text within content for the first time.
【stringToFind】is the specific text to search for.
【whereToSearch】specifies the content to search within. You can input text parameters or reference fields.
【startFromPosition】optional, specifies the position to start searching from (using a number to indicate the character position).
This function can quickly search for the position of specific text within a large content.
If it returns the number 3, it means the text appears at the 3rd character of the content.
If no matching text is found, the result will be empty.
It is similar to FIND(), but when no match is found, FIND() returns 0 instead of an empty value.
