• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) OR (sach thu)) hang xa hoi. hieu va cam xuc va ((thanh vien) or (thanh ha)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach thu)) hang xa hoi. hieu va cam xuc va ((thanh vien) OR (thanh ha)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach thu)) hang xa hoi. hieu va cam xuc va ((thanh vien) or (thanh ha)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach thu)) hang xa hoi. hieu va cam xuc va ((thanh vien) or (thanh ha)) cua tre*.
