• Performing a fuzzy search may retrieve terms with similar spellings: su sach thue dang xa hoi. hieu ve pham duc ((van anh) OR (tuan anh)) vai ((cua tre) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thue dang xa hoi. hieu ve pham duc ((van anh) OR (tuan anh)) vai ((cua tre) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thue dang xa hoi. hieu ve pham duc ((van anh) OR (tuan anh)) vai ((cua tre) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: su sach thue dang xa hoi. hieu ve pham duc ((van anh) OR (tuan anh)) vai ((cua tre) or (cua tu))*.
