171.2 early » 1712 early, 17.2 early, 1715 early
f commerce » _ commerce, m commerce, a commerce
1.2 early » 12 early, 1722 early, 1702 early
21 green » 1 green, 11 green
2f early » 24 early, 20 early, 21 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: %22india %f commerce %((21 green) OR (2011 great)) britain %((((2f early) OR (f early))) OR (((1.2 early) OR (((171.2 early) OR (1714 early)))))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22india %f commerce %((21 green) or (2011 great)) britain %((((2f early) or (f early))) or (((1.2 early) or (((171.2 early) OR (1714 early)))))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22india %f commerce %((21 green) or (2011 great)) britain %((((2f early) or (f early))) or (((1.2 early) or (((171.2 early) OR (1714 early)))))) works to 1800%22*.
