• If you are trying to use Boolean operators, they must be ALL CAPS: ((((violence index) OR (violence india))) OR (violence under)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((violence index) OR (violence india))) or (violence under))".
• Adding a wildcard symbol may retrieve word variants: ((((violence index) OR (violence india))) or (violence under))*.
