Perhaps you should try some spelling variations:
2 fixation » n2 fixation, _ fixation, 4 fixation
1720 early » 1727 early, 1770 early, 1722 early
2 fiction » 2 fission, 1792 fiction, 1902 fiction
2f early » 24 early, 21 early, 23 early
22 early » 2 early, 12 early, 1722 early
20 early » 10 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 %((2 fiction) OR (2 fixation)) %((((2f early) OR (22 early))) OR (((20 early) OR (((1720 early) OR (1820 early)))))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ethiopia %((2 fiction) OR (2 fixation)) %((((2f early) or (22 early))) or (((20 early) or (((1720 early) or (1820 early)))))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22ethiopia %((2 fiction) OR (2 fixation)) %((((2f early) or (22 early))) or (((20 early) or (((1720 early) or (1820 early)))))) works to 1800%22*.
