When I enter your entire sentence I get a strange result I've never seen
before.
It erases the line. Then splits it. The result is almost correct. Maybe
some of the real experts can explain this behavior.
2 3 5 +(1 : '[
by ] over [ u/ ]') 0 1 2 3

Could the adverb part be done this way? If so, the verb part could be
changed, too.
