Try this formula in C2, then copied down:
=IFERROR(LOOKUP(2, 1/(ISNUMBER(SEARCH($X$3:$X$7, B2))), $Y$3:$Y$7), "")
This will give you matches that DO exist. Then you can scan the data looking for variations and expand your X:Y table to include more variations till you get them all.
Letting the techs enter anything is the problem, you'll have to deal with it in some manual way until such time you DO get data validated entries.
