• If you are trying to use Boolean operators, they must be ALL CAPS: ((((alexander watson) OR (alexander alison))) OR (alexander wilson)) (historian)*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((alexander watson) OR (alexander alison))) or (alexander wilson)) (historian)*".
