• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky dang xa hoi. hieu van cam xuc ((vu dinh) or (van dinh)) ((vai cau) OR (vai cac)) treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky dang xa hoi. hieu van cam xuc ((vu dinh) OR (van dinh)) ((vai cau) OR (vai cac)) treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky dang xa hoi. hieu van cam xuc ((vu dinh) or (van dinh)) ((vai cau) OR (vai cac)) treo".
• Adding a wildcard symbol may retrieve word variants: thu sac ky dang xa hoi. hieu van cam xuc ((vu dinh) or (van dinh)) ((vai cau) OR (vai cac)) treo*.
