• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((ky dang) OR (ky nang)) xay hoi. hieu ((ve cai) or (ve cham)) duc ban anh hai cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ky dang) OR (ky nang)) xay hoi. hieu ((ve cai) OR (ve cham)) duc ban anh hai cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ky dang) OR (ky nang)) xay hoi. hieu ((ve cai) or (ve cham)) duc ban anh hai cua viet".
• Adding a wildcard symbol may retrieve word variants: su sach ((ky dang) OR (ky nang)) xay hoi. hieu ((ve cai) or (ve cham)) duc ban anh hai cua viet*.
