» Finding a substring within a string

Problem:

Determining whether the strings in column C contain the corresponding substrings in column D.
Solution 1:
Using the COUNTIF function in the following IF statement:
=IF(COUNTIF(A2,""*""&B2&""*"")>0,""Found"",""Not Found"")


Solution 2:
Using the ISNUMBER and FIND functions, as follows:
=IF(ISNUMBER(FIND(B2,A2)),""Found"",""Not Found"")


Example:

String_____Substring to Find____Result
abc________abc__________________Found
abcdef_____cde__________________Found
abde_______bc___________________Not Found
abcdefgh___fgh__________________Found
