• Performing a fuzzy search may retrieve terms with similar spellings: (("van hoc hoi ky van vuong.") OR ((("van hoc hoi ky va cuong.") OR ("van hoc ha ky va cuong."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"van hoc hoi ky van vuong.\") OR (((\"van hoc hoi ky va cuong.\") OR (\"van hoc ha ky va cuong.\"))))".
• Removing quotes may allow a broader search: (( van hoc hoi ky van vuong. ) OR ((( van hoc hoi ky va cuong. ) OR ( van hoc ha ky va cuong. )))).
• Adding a wildcard symbol may retrieve word variants: (("van hoc hoi ky van vuong.") OR ((("van hoc hoi ky va cuong.") OR ("van hoc ha ky va cuong."))))*.
