• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ky nang x hoi. lieu va cham ((xuc ban) OR (duc ban)) anh de cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang x hoi. lieu va cham ((xuc ban) OR (duc ban)) anh de cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky nang x hoi. lieu va cham ((xuc ban) OR (duc ban)) anh de cua tre*".
