Perhaps you should try some spelling variations:
2f fiction » f fiction, 2 fiction, a fiction
1720 early » 1820 early, 1770 early, 1722 early
2f early » 21 early, f early, sf early
22 early » 12 early, 1722 early, 1.2 early
20 early » 10 early, 1820 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 (((22 early) OR (2 early))))) OR (((20 early) OR (((1720 early) OR (1727 early)))))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ethiopia %2f fiction %((((2f early) or (((22 early) or (2 early))))) or (((20 early) or (((1720 early) OR (1727 early)))))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22ethiopia %2f fiction %((((2f early) or (((22 early) or (2 early))))) or (((20 early) or (((1720 early) OR (1727 early)))))) works to 1800%22*.
