Perhaps you should try some spelling variations:
2.1 description » 3.1 description, 5.1 description, 4.1 description
2f description » 20 description, 2.2 description, 2.3 description
f description » 7 description, self description, 2.2 description
2f early » 20 early, ef early, f early
21 early » 2.1 early, 1 early, 11 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: %22bromley %28london%((3 england) OR (((((6 england) OR (5 england))) OR (_ england))))%29 %((((2f description) OR (2.1 description))) OR (f description)) AND travel %((2f early) OR (21 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bromley %28london%((3 england) or (((((6 england) or (5 england))) or (_ england))))%29 %((((2f description) or (2.1 description))) or (f description)) and travel %((2f early) OR (21 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bromley %28london%((3 england) or (((((6 england) or (5 england))) or (_ england))))%29 %((((2f description) or (2.1 description))) or (f description)) and travel %((2f early) OR (21 early)) works to 1800%22*.
