• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"((sarah ann) OR (sarah a)) smith\\") OR (((\\"sarah abd smith\\") OR (\\"sarah m smith\\"))))\"".
• Removing quotes may allow a broader search: (( ((sarah ann) OR (sarah a)) smith ) OR ((( sarah abd smith ) OR ( sarah m smith )))).
