• Performing a fuzzy search may retrieve terms with similar spellings: thu xac ky nang xa hoi. hieu ve ((cao duc) OR (dao duc)) va nhan ((vien cua) or (tien cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu xac ky nang xa hoi. hieu ve ((cao duc) OR (dao duc)) va nhan ((vien cua) OR (tien cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu xac ky nang xa hoi. hieu ve ((cao duc) OR (dao duc)) va nhan ((vien cua) or (tien cua)) te".
• Adding a wildcard symbol may retrieve word variants: thu xac ky nang xa hoi. hieu ve ((cao duc) OR (dao duc)) va nhan ((vien cua) or (tien cua)) te*.
