• If you are trying to use Boolean operators, they must be ALL CAPS: %22great britain %ref history %((4 georges) OR (_ georges)) iii%((2c 1727) OR (29 1727))-1760 %((((2f early) OR (21 early))) OR (1720 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22great britain %ref history %((4 georges) or (_ georges)) iii%((2c 1727) or (29 1727))-1760 %((((2f early) OR (21 early))) or (1720 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22great britain %ref history %((4 georges) or (_ georges)) iii%((2c 1727) or (29 1727))-1760 %((((2f early) OR (21 early))) or (1720 early)) works to 1800%22*.
