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