INSTR() searches for the search string in the other string. INSTR() returns the character index of the nth occurrence of the search string in the other string, starting from the left side of the string. If no occurrence number is specified, INSTR() returns the first occurrence, starting from the left side of the string. If the search string cannot be found or the occurrence number listed runs past the end of the input string, INSTR() returns zero.


NOTE: INSTR() is an alias for LFIND()
