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