• If you are trying to use Boolean operators, they must be ALL CAPS: (("imaginary confessions") OR ((("binary expressions") OR ("binary regression")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"imaginary confessions\") or (((\"binary expressions\") OR (\"binary regression\"))))".
• Removing quotes may allow a broader search: (( imaginary confessions ) or ((( binary expressions ) OR ( binary regression )))).
• Adding a wildcard symbol may retrieve word variants: (("imaginary confessions") or ((("binary expressions") OR ("binary regression"))))*.
