• Performing a fuzzy search may retrieve terms with similar spellings: (( thu sach cha ((me nguoi) OR (ma nguoi)) moi thong tin ) or ( su sach xa me gioi co dong von ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach cha ((me nguoi) OR (ma nguoi)) moi thong tin ) OR ( su sach xa me gioi co dong von )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach cha ((me nguoi) OR (ma nguoi)) moi thong tin ) or ( su sach xa me gioi co dong von ))".
• Adding a wildcard symbol may retrieve word variants: (( thu sach cha ((me nguoi) OR (ma nguoi)) moi thong tin ) or ( su sach xa me gioi co dong von ))*.
