• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty hang xa hoi. ki ((nang cam) OR (nang cham)) ((luc va) or (thuc dan)) hanh vai cu tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hang xa hoi. ki ((nang cam) OR (nang cham)) ((luc va) OR (thuc dan)) hanh vai cu tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hang xa hoi. ki ((nang cam) OR (nang cham)) ((luc va) or (thuc dan)) hanh vai cu tren".
• Adding a wildcard symbol may retrieve word variants: tu sach ty hang xa hoi. ki ((nang cam) OR (nang cham)) ((luc va) or (thuc dan)) hanh vai cu tren*.
