• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu nang x hoi. thien van ((nam qua) OR (nam cua)) van ((hanh di) OR (hanh de)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu nang x hoi. thien van ((nam qua) OR (nam cua)) van ((hanh di) or (hanh de)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach tu nang x hoi. thien van ((nam qua) OR (nam cua)) van ((hanh di) or (hanh de)) cua tre*.
