Perhaps you should try some spelling variations:
2f fiction » f fiction, 2 fiction, a fiction
1710 early » 1714 early, 1715 early, 1770 early
2f early » 21 early, f early, sf early
20 early » 1820 early, 1720 early
22 early » 12 early, 1722 early, 1.2 early
10 early » 1800 early, 1820 early, 1770 early

Try widening your search to All Fields.

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: %22ethiopia %2f fiction %((((((2f early) OR (20 early))) OR (((22 early) OR (2 early))))) OR (((10 early) OR (1710 early)))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ethiopia %2f fiction %((((((2f early) OR (20 early))) or (((22 early) or (2 early))))) or (((10 early) or (1710 early)))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22ethiopia %2f fiction %((((((2f early) OR (20 early))) or (((22 early) or (2 early))))) or (((10 early) or (1710 early)))) works to 1800%22*.
