SUMPRODUCT with fuzzy wildcard search but also with NOT statement

[useless at my job really]

Hello all

I have a working formula that will provide me a count on the basis of explicitly stated search criteria, a fuzzy 'wildcard' based search. It is the following:

=SUMPRODUCT(($A$4:$A$2851=$M8)*(--(ISNUMBER(SEARCH(N$2,$C$4:$I$2851))*(--(ISNUMBER(SEARCH($L8,$C$4:$I$2851)))))))

However, as part of this count I would like to exclude the count from any cells that contain for instance the word 'boost'. To achieve this, in cell J9 I have written *boost* and changed the formula to the following:

=SUMPRODUCT(($A$4:$A$2851=$M9)*(--(ISNUMBER(SEARCH(N$2,$C$4:$I$2851))*(--(ISNUMBER(SEARCH($L9,$C$4:$I$2851)*(--(NOT(ISNUMBER(SEARCH($J9,$C$4:$I$2851)))))))))))`

This however has not excluded any matches that also include the term 'boost' in the cell. It simply produces exactly the same count as before.

Could any help possibly be given with this please?

Much appreciated

You have misplaced brackets plus you dont need the * in the cell. Try this:

=SUMPRODUCT(($A$4:$A$2851=$M9)*(ISNUMBER(SEARCH(N$2,$C$4:$I$2851)))*(ISNUMBER(SEARCH($L9,$C$4:$I$2851)))*(NOT(ISNUMBER(SEARCH($J9,$C$4:$I$2851)))))

Thank you very much Steve ! Appears to work perfectly. I guess I don't need the -- prefix to the isnumber then. Also good to know I don't need the * when searching the cell - I guess this is only perhaps needed with SUMIFS / Index Match etc.

Hope I can be a credit to the world with something like what you do one day !
