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