• Performing a fuzzy search may retrieve terms with similar spellings: vu (((bach OR bac) mai) or (ban moi)) tap, nghien cuu mot hoc nganh khoa hoc ma hoi danh nhan dan~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu (((bach OR bac) mai) OR (ban moi)) tap, nghien cuu mot hoc nganh khoa hoc ma hoi danh nhan dan.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu (((bach OR bac) mai) or (ban moi)) tap, nghien cuu mot hoc nganh khoa hoc ma hoi danh nhan dan".
• Adding a wildcard symbol may retrieve word variants: vu (((bach OR bac) mai) or (ban moi)) tap, nghien cuu mot hoc nganh khoa hoc ma hoi danh nhan dan*.
