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