• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (toc thieu)) xanh - ((hanh trinh) OR (canh tranh)) ve nhung truong van thang tam~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (toc thieu)) xanh - ((hanh trinh) OR (canh tranh)) ve nhung truong van thang tam~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) or (toc thieu)) xanh - ((hanh trinh) OR (canh tranh)) ve nhung truong van thang tam*.
