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