Perhaps you should try some spelling variations:
2f fiction » f fiction, 2 fiction, _ fiction
1720 early » 1727 early, 1820 early, 1770 early
1.2 early » 12 early, 1722 early, 1702 early
2f early » 24 early, 21 early, 23 early
sf early » ef early, self early, imf early
20 early » 10 early, 1820 early
22 early » 12 early, 1722 early
f early » ef early, 7 early, 8 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: %22ethiopia %2f fiction %((((((((2f early) OR (sf early))) OR (f early))) OR (((((22 early) OR (1.2 early))) OR (17((22 early) OR (1.2 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 (sf early))) or (f early))) or (((((22 early) or (1.2 early))) or (17((22 early) or (1.2 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 (sf early))) or (f early))) or (((((22 early) or (1.2 early))) or (17((22 early) or (1.2 early))))))) or (((20 early) or (1720 early)))) works to 1800%22*.
