• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((((mang xa) OR (lang xa))) or (nang x)) hoi. hieu van lam thuoc phap thinh le cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((((mang xa) OR (lang xa))) OR (nang x)) hoi. hieu van lam thuoc phap thinh le cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((((mang xa) OR (lang xa))) or (nang x)) hoi. hieu van lam thuoc phap thinh le cua tre*".
