• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sac ky) or (sach ty)) ((tang lai) OR (trang lai)) hoi. hieu ve cham xuc van luan van cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sac ky) OR (sach ty)) ((tang lai) OR (trang lai)) hoi. hieu ve cham xuc van luan van cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sac ky) or (sach ty)) ((tang lai) OR (trang lai)) hoi. hieu ve cham xuc van luan van cua tu*".
