• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"danh tac van hoan thien nay\") OR (\"danh bac van hoc hien nam\"))~".
• Removing quotes may allow a broader search: (( danh tac van hoan thien nay ) OR ( danh bac van hoc hien nam ))~.
• Adding a wildcard symbol may retrieve word variants: (("danh tac van hoan thien nay") OR ("danh bac van hoc hien nam"))*.
