• If you are trying to use Boolean operators, they must be ALL CAPS: (("online random search document") OR ((("online hand research comments") OR ("online band research comments"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"online random search document\") or (((\"online hand research comments\") OR (\"online band research comments\"))))*".
• Removing quotes may allow a broader search: (( online random search document ) or ((( online hand research comments ) OR ( online band research comments ))))*.
