• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((lieu tinh) OR (diep tinh)) - hanh dung cua nhung cong van ((quang ban) or (quang bang))~".
• Adding a wildcard symbol may retrieve word variants: ho ((lieu tinh) OR (diep tinh)) - hanh dung cua nhung cong van ((quang ban) or (quang bang))*.
