• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sang - ((hanh tang) OR (hanh trang)) va huong vuong ((manh toan) or (thanh toan)) cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((hanh tang) OR (hanh trang)) va huong vuong ((manh toan) OR (thanh toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((hanh tang) OR (hanh trang)) va huong vuong ((manh toan) or (thanh toan)) cao".
