• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach tu) OR (sach thu)) ((nang xa) or (lang xa)) hoi. hieu ve cam suc manh hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach tu) OR (sach thu)) ((nang xa) OR (lang xa)) hoi. hieu ve cam suc manh hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach tu) OR (sach thu)) ((nang xa) or (lang xa)) hoi. hieu ve cam suc manh hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sach tu) OR (sach thu)) ((nang xa) or (lang xa)) hoi. hieu ve cam suc manh hanh vai cuu tre*.
