• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ((v nang) or (((lv nang) OR (ly nang)))) x hoi. hieu ve cao duc va danh gia cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((v nang) OR (((lv nang) OR (ly nang)))) x hoi. hieu ve cao duc va danh gia cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((v nang) or (((lv nang) OR (ly nang)))) x hoi. hieu ve cao duc va danh gia cua triet*".
