• Performing a fuzzy search may retrieve terms with similar spellings: su ((((sach ky) OR (sach ty))) or (sac ky)) nang xa hoi. hieu ve cham xuc va han tai va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((((sach ky) OR (sach ty))) OR (sac ky)) nang xa hoi. hieu ve cham xuc va han tai va thiet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((((sach ky) OR (sach ty))) or (sac ky)) nang xa hoi. hieu ve cham xuc va han tai va thiet".
• Adding a wildcard symbol may retrieve word variants: su ((((sach ky) OR (sach ty))) or (sac ky)) nang xa hoi. hieu ve cham xuc va han tai va thiet*.
