• Performing a fuzzy search may retrieve terms with similar spellings: ((xuyen tai) or (truyen tai)) cach thuc đe co ban kem ((tay tieng) OR (ta tieng)) dung cong~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((xuyen tai) OR (truyen tai)) cach thuc đe co ban kem ((tay tieng) OR (ta tieng)) dung cong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((xuyen tai) or (truyen tai)) cach thuc đe co ban kem ((tay tieng) OR (ta tieng)) dung cong".
• Adding a wildcard symbol may retrieve word variants: ((xuyen tai) or (truyen tai)) cach thuc đe co ban kem ((tay tieng) OR (ta tieng)) dung cong*.
