Perhaps you should try some spelling variations:
1720 early » 1727 early, 1820 early, 1770 early
20 france » 10 france, 20 fringe
2f early » 24 early, 21 early, 22 early
20 early » 10 early, 1820 early
21 law » 21 low

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: %22coinage %((21 law) OR (11 law)) AND legislation %20 france %((2f early) OR (((20 early) OR (1720 early)))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22coinage %((21 law) OR (11 law)) and legislation %20 france %((2f early) or (((20 early) or (1720 early)))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22coinage %((21 law) OR (11 law)) and legislation %20 france %((2f early) or (((20 early) or (1720 early)))) works to 1800%22*.
