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