• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((huy hoang) or (duy hoang)) van hoi. hieu va dat nuoc va ((hanh di) OR (hang di)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((huy hoang) OR (duy hoang)) van hoi. hieu va dat nuoc va ((hanh di) OR (hang di)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((huy hoang) or (duy hoang)) van hoi. hieu va dat nuoc va ((hanh di) OR (hang di)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((huy hoang) or (duy hoang)) van hoi. hieu va dat nuoc va ((hanh di) OR (hang di)) cuu tre*.
