Word search in Excel

Is there a function that can search the entire worksheet (all columns & rows) for a given word that the user inputs and then the output would be the cell(s) location(s) that contains the user supplied word that was the input? For example: A1 is the cell that all queried words will be entered by the user and B1 is where the results are returned. If we are wanting to find all locations of the word "Cost" which are in G8, Y2 and F26. Then after Excel performs the search it would return in B1 "G8,Y2,F26". Is this something that's possible? Thank you so much for the help!
