• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach tu) OR (sach thu)) xang xa hoi. hieu ve ((cau phuc) or (cam xuc)) van dinh ve cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach tu) OR (sach thu)) xang xa hoi. hieu ve ((cau phuc) OR (cam xuc)) van dinh ve cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach tu) OR (sach thu)) xang xa hoi. hieu ve ((cau phuc) or (cam xuc)) van dinh ve cua tre*".
