• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (thuat san)) ky ((lang xa) OR (lang ha)) hoi. hieu ve cac duc va thanh moi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (thuat san)) ky ((lang xa) OR (lang ha)) hoi. hieu ve cac duc va thanh moi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (thuat san)) ky ((lang xa) OR (lang ha)) hoi. hieu ve cac duc va thanh moi cua tre".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (thuat san)) ky ((lang xa) OR (lang ha)) hoi. hieu ve cac duc va thanh moi cua tre*.
