• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang cao hoc. hieu vu cham xuc ((va hanh) or (va dan)) dau ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang cao hoc. hieu vu cham xuc ((va hanh) OR (va dan)) dau ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang cao hoc. hieu vu cham xuc ((va hanh) or (va dan)) dau ((cua tre) OR (cuu tre))".
