• If you are trying to use Boolean operators, they must be ALL CAPS: (( my big heads deep lying ) OR ( my ((big part) OR (big start)) great reading )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( my big heads deep lying ) or ( my ((big part) OR (big start)) great reading ))".
• Adding a wildcard symbol may retrieve word variants: (( my big heads deep lying ) or ( my ((big part) OR (big start)) great reading ))*.
