When using any version of !lookup, if the submitted string does not return any matches, remove all spaces from the string and redo the search one more time.
Currently it's fairly common to see people fail a lookup query because they added unnecessary spaces. I know there are other ways to make a search more resilient against whitespace, but I suspect those solutions would take longer and be more involved to implement, so I'm suggesting this simpler solution in its stead.
If this enhancement is implemented, I will review the json data and remove whitespaces from all the aliases.
