• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ky lang) OR (ky dang)) xa hoi. hieu van lam xuc va ((dan vai) or (dan tai)) cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky lang) OR (ky dang)) xa hoi. hieu van lam xuc va ((dan vai) OR (dan tai)) cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky lang) OR (ky dang)) xa hoi. hieu van lam xuc va ((dan vai) or (dan tai)) cau treo*".
