• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh ((trang va) OR (tran van)) ((nhung huong) OR (nhung phuong)) dan van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((trang va) OR (tran van)) ((nhung huong) or (nhung phuong)) dan van ban".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh ((trang va) OR (tran van)) ((nhung huong) or (nhung phuong)) dan van ban*.
