• Performing a fuzzy search may retrieve terms with similar spellings: ((((tu sach) OR (su sach))) or (thu hoach)) ty nang xa hoi. hieu qua ca xuc va hanh va cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (su sach))) OR (thu hoach)) ty nang xa hoi. hieu qua ca xuc va hanh va cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (su sach))) or (thu hoach)) ty nang xa hoi. hieu qua ca xuc va hanh va cua triet".
• Adding a wildcard symbol may retrieve word variants: ((((tu sach) OR (su sach))) or (thu hoach)) ty nang xa hoi. hieu qua ca xuc va hanh va cua triet*.
