I have tried the function search and find, both functions are working when

Does anyone have any suggestions?

If by "fuzzy matching" you mean matching "apple" when it exists anyplace within
the string, my suggestion is that you read about and try out the SEARCH and
FIND functions. Be sure in your reading to consider the slight difference
between the two.
