• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ky dang mau hoa. hieu ve cac tuc va hanh ((may duc) OR (mai duc)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky dang mau hoa. hieu ve cac tuc va hanh ((may duc) OR (mai duc)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky dang mau hoa. hieu ve cac tuc va hanh ((may duc) OR (mai duc)) tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ky dang mau hoa. hieu ve cac tuc va hanh ((may duc) OR (mai duc)) tre*.
