Perhaps you should try some spelling variations:
22business ethics » business ethics, iii.business ethics, business ethical
1722 early » 1727 early
2f poetry » 28 poetry, 2 poetry, 20 poetry
10 early » 1800 early, 1820 early, 1770 early
23 early » 2.3 early, 3 early, 13 early
22 early » 2 early, 1.2 early
12 early » 2 early, 1702 early, 7 early
11 early » 1 early, 1791 early, 7 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 %2f poetry %((((10 early) OR (23 early))) OR (((((22 early) OR (1722 early))) OR (((12 early) OR (11 early)))))) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22business ethics %2f poetry %((((10 early) or (23 early))) or (((((22 early) OR (1722 early))) or (((12 early) or (11 early)))))) works to 1800%22*".
