I had the same issue and of course I could not force user to do some extra stuff when composing their word document so I decided to just write an algo to scan the whole document for expressions appending run after run, inserting replacement value and remove expressions in the second run. In case other people may need it below is what I did. I got the class from somewhere so it may be familiar. I just added the method searchAndReplace()
