• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky ((song xa) or (song cua)) hoi. hieu va cham ((xuc van) OR (duc van)) anh lai va trien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky ((song xa) OR (song cua)) hoi. hieu va cham ((xuc van) OR (duc van)) anh lai va trien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky ((song xa) or (song cua)) hoi. hieu va cham ((xuc van) OR (duc van)) anh lai va trien".
• Adding a wildcard symbol may retrieve word variants: thu sach ky ((song xa) or (song cua)) hoi. hieu va cham ((xuc van) OR (duc van)) anh lai va trien*.
