• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach tu) OR (sach thu)) xang xa hoi. hieu ve ((cau luc) or (cam xuc)) va dinh le cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (sach thu)) xang xa hoi. hieu ve ((cau luc) OR (cam xuc)) va dinh le cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) OR (sach thu)) xang xa hoi. hieu ve ((cau luc) or (cam xuc)) va dinh le cau treo".
• Adding a wildcard symbol may retrieve word variants: te ((sach tu) OR (sach thu)) xang xa hoi. hieu ve ((cau luc) or (cam xuc)) va dinh le cau treo*.
