Perhaps you should try some spelling variations:
2.1 early » 11 early
1.1 early » 11 early, 1791 early, 1771 early
2f early » 24 early, 20 early, 22 early
21 early » 11 early
f early » ef early, sf early, 7 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: %22opera %((((2f early) OR (f early))) OR (((((21 early) OR (((2.1 early) OR (1.1 early))))) OR (1 early)))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22opera %((((2f early) or (f early))) or (((((21 early) or (((2.1 early) OR (1.1 early))))) or (1 early)))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22opera %((((2f early) or (f early))) or (((((21 early) or (((2.1 early) OR (1.1 early))))) or (1 early)))) works to 1800%22*.
