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