• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (thuat lanh)) y nang x ho. hieu ve cac duc manh minh cu ((va triet) OR (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat lanh)) y nang x ho. hieu ve cac duc manh minh cu ((va triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (thuat lanh)) y nang x ho. hieu ve cac duc manh minh cu ((va triet) OR (ve triet))".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (thuat lanh)) y nang x ho. hieu ve cac duc manh minh cu ((va triet) OR (ve triet))*.
