Perhaps you should try some spelling variations:
2f fiction » f fiction, 2 fiction, a fiction
1720 early » 1727 early, 1820 early, 1770 early
2f early » 21 early, 22 early, sf early
12 early » 11 early, 1722 early, 1702 early
20 early » 10 early, 1820 early
f early » sf early, 5 early, 8 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 (f early))) OR (((12 early) OR (2 early))))) OR (((20 early) OR (1720 early)))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ethiopia %2f fiction %((((((2f early) OR (f early))) or (((12 early) or (2 early))))) or (((20 early) or (1720 early)))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22ethiopia %2f fiction %((((((2f early) OR (f early))) or (((12 early) or (2 early))))) or (((20 early) or (1720 early)))) works to 1800%22*.
