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