• Performing a fuzzy search may retrieve terms with similar spellings: tu ((((sach ky) OR (sac ky))) or (sach y)) lang xa hoi. hieu va cam loc va hang tai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach ky) OR (sac ky))) OR (sach y)) lang xa hoi. hieu va cam loc va hang tai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((((sach ky) OR (sac ky))) or (sach y)) lang xa hoi. hieu va cam loc va hang tai cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((((sach ky) OR (sac ky))) or (sach y)) lang xa hoi. hieu va cam loc va hang tai cua te*.
