• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) or (sach y)) dang xay hoi. thien van cau xuc va dinh ((va cau) OR (va dau)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) dang xay hoi. thien van cau xuc va dinh ((va cau) OR (va dau)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach y)) dang xay hoi. thien van cau xuc va dinh ((va cau) OR (va dau)) tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach y)) dang xay hoi. thien van cau xuc va dinh ((va cau) OR (va dau)) tre*.
