I currently have a workflow which uses the contains() function to search through a column:

The issue I am having is I only want to find the exact words specified in my excel input, but contains() will return a positive result even if a word happens to be within a word in my input file e.g. if i want to search for "hug", the workflow returns a positive value whenever it finds the word "huge"; but I only want to see a positive result if the exact word is found.
Any ideas?
