2f poetry » 28 poetry, 2 poetry, 20 poetry
2sf early » 2.1 early, 2.3 early, 24 early
sf early » ef early, f early, self early
22 early » 2 early, 1722 early, 1.2 early
12 early » 2 early, 11 early, 1722 early

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %((22business ethics) OR (business ethics)) %2f poetry %((((2sf early) OR (sf early))) OR (((22 early) OR (12 early)))) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22business ethics) or (business ethics)) %2f poetry %((((2sf early) or (sf early))) or (((22 early) OR (12 early)))) works to 1800%22*".
