• Performing a fuzzy search may retrieve terms with similar spellings: (((("danh ca van hoc hien nam") or ("dan ca van thuoc phien nam"))) or ((("dan cac van hoc hien dai") OR ("dan cach van hoc hien dai"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("danh ca van hoc hien nam") OR ("dan ca van thuoc phien nam"))) OR ((("dan cac van hoc hien dai") OR ("dan cach van hoc hien dai")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"danh ca van hoc hien nam\") or (\"dan ca van thuoc phien nam\"))) or (((\"dan cac van hoc hien dai\") OR (\"dan cach van hoc hien dai\"))))".
• Removing quotes may allow a broader search: (((( danh ca van hoc hien nam ) or ( dan ca van thuoc phien nam ))) or ((( dan cac van hoc hien dai ) OR ( dan cach van hoc hien dai )))).
• Adding a wildcard symbol may retrieve word variants: (((("danh ca van hoc hien nam") or ("dan ca van thuoc phien nam"))) or ((("dan cac van hoc hien dai") OR ("dan cach van hoc hien dai"))))*.
