• Performing a fuzzy search may retrieve terms with similar spellings: ((ho cuu) OR (so cuu)) tinh - ((hanh trang) or (canh tranh)) va hang cong vang tuan cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho cuu) OR (so cuu)) tinh - ((hanh trang) OR (canh tranh)) va hang cong vang tuan cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho cuu) OR (so cuu)) tinh - ((hanh trang) or (canh tranh)) va hang cong vang tuan cu".
• Adding a wildcard symbol may retrieve word variants: ((ho cuu) OR (so cuu)) tinh - ((hanh trang) or (canh tranh)) va hang cong vang tuan cu*.
