• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. hieu van chat xuc cam ((dan vai) OR (dan va)) ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu van chat xuc cam ((dan vai) OR (dan va)) ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. hieu van chat xuc cam ((dan vai) OR (dan va)) ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. hieu van chat xuc cam ((dan vai) OR (dan va)) ((cua tre) or (cua te))*.
