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