• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) or (sach y)) sang tao hoi. hieu van cam xuc ban ((anh vi) OR (anh va)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) sang tao hoi. hieu van cam xuc ban ((anh vi) OR (anh va)) va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach y)) sang tao hoi. hieu van cam xuc ban ((anh vi) OR (anh va)) va triet*".
