• Performing a fuzzy search may retrieve terms with similar spellings: so sanh ky nang x hoi. hieu van ((tham xuc) or (tham nuoc)) va danh van ((cau tren) OR (dau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky nang x hoi. hieu van ((tham xuc) OR (tham nuoc)) va danh van ((cau tren) OR (dau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky nang x hoi. hieu van ((tham xuc) or (tham nuoc)) va danh van ((cau tren) OR (dau tren))".
• Adding a wildcard symbol may retrieve word variants: so sanh ky nang x hoi. hieu van ((tham xuc) or (tham nuoc)) va danh van ((cau tren) OR (dau tren))*.
