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