• Performing a fuzzy search may retrieve terms with similar spellings: te bai ((ky lang) OR (ky nang)) xa hoi. hieu va cham luc va ((thanh tai) or (han tai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te bai ((ky lang) OR (ky nang)) xa hoi. hieu va cham luc va ((thanh tai) OR (han tai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te bai ((ky lang) OR (ky nang)) xa hoi. hieu va cham luc va ((thanh tai) or (han tai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te bai ((ky lang) OR (ky nang)) xa hoi. hieu va cham luc va ((thanh tai) or (han tai)) cua tre*.
