• Performing a fuzzy search may retrieve terms with similar spellings: te ((((sach ky) OR (sach ty))) or (sach y)) nang cai hoi. thi van nam xuc ca dan va cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach ky) OR (sach ty))) OR (sach y)) nang cai hoi. thi van nam xuc ca dan va cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ky) OR (sach ty))) or (sach y)) nang cai hoi. thi van nam xuc ca dan va cua triet*".
