You're adding two terms there where you actually want to add
five. Ignoring stemming, you want:

X1spaghetti
X1pizza
X2cars
X2party
X2friends

Possibly the easiest way of generating terms is to use the
TermGenerator. The introductory docs are a little difficult to read as
they are mostly documenting the changes from previous versions, but
the API docs should help.

Well, it won't be that, it'll be (ZX2party:(pos=1) OR
ZX2friends:(pos=2)) or something very similar. If you construct terms
as above, you'll be fine.
