• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ky ((tang ma) OR (tang van)) hoi. hieu ((ve cam) or (va cam)) luc anh tuan vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky ((tang ma) OR (tang van)) hoi. hieu ((ve cam) OR (va cam)) luc anh tuan vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky ((tang ma) OR (tang van)) hoi. hieu ((ve cam) or (va cam)) luc anh tuan vai cua triet".
• Adding a wildcard symbol may retrieve word variants: thuoc sach ky ((tang ma) OR (tang van)) hoi. hieu ((ve cam) or (va cam)) luc anh tuan vai cua triet*.
