• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc hieu) OR (doc hieu)) manh - hanh trung ((cua phuong) or (cuc phuong)) dung dan tuan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc hieu) OR (doc hieu)) manh - hanh trung ((cua phuong) OR (cuc phuong)) dung dan tuan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hieu) OR (doc hieu)) manh - hanh trung ((cua phuong) or (cuc phuong)) dung dan tuan ban*".
