• Performing a fuzzy search may retrieve terms with similar spellings: tu sach v lang xa hoi. hieu va dau xuc ((van anh) or (tuan anh)) ((vai cuu) OR (vai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v lang xa hoi. hieu va dau xuc ((van anh) OR (tuan anh)) ((vai cuu) OR (vai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v lang xa hoi. hieu va dau xuc ((van anh) or (tuan anh)) ((vai cuu) OR (vai cua)) tre*".
