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