• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu lang) OR (((hieu quang) OR (thieu quang)))) - hanh trung tuan hang cong dan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu lang) or (((hieu quang) OR (thieu quang)))) - hanh trung tuan hang cong dan than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) or (((hieu quang) OR (thieu quang)))) - hanh trung tuan hang cong dan than cau*.
