• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu khac)) ky nang xa hoi. hieu ve cham sac van anh ((di cua) OR (de cua)) viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu khac)) ky nang xa hoi. hieu ve cham sac van anh ((di cua) OR (de cua)) viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu khac)) ky nang xa hoi. hieu ve cham sac van anh ((di cua) OR (de cua)) viet*".
