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