• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"trinh luat quan van thien hoat\") OR (\"dinh dan quan van chien soat\"))~".
• Removing quotes may allow a broader search: (( trinh luat quan van thien hoat ) OR ( dinh dan quan van chien soat ))~.
• Adding a wildcard symbol may retrieve word variants: (("trinh luat quan van thien hoat") OR ("dinh dan quan van chien soat"))*.
