• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty hang ca hoi. lieu va cam ((xuc va) OR (luc va)) dinh di ((cua triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang ca hoi. lieu va cam ((xuc va) OR (luc va)) dinh di ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang ca hoi. lieu va cam ((xuc va) OR (luc va)) dinh di ((cua triet) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ty hang ca hoi. lieu va cam ((xuc va) OR (luc va)) dinh di ((cua triet) or (su triet))*.
