• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((ky dang) OR (ky nang)) xay hoi. ((hieu ve) or (hieu va)) cam xuc ban lanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ky dang) OR (ky nang)) xay hoi. ((hieu ve) OR (hieu va)) cam xuc ban lanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ky dang) OR (ky nang)) xay hoi. ((hieu ve) or (hieu va)) cam xuc ban lanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ((ky dang) OR (ky nang)) xay hoi. ((hieu ve) or (hieu va)) cam xuc ban lanh hai cua tre*.
