• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ((y nang) OR (ly nang)) dai hoi. ((hieu ve) OR (hieu van)) cao duc minh anh hai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ((y nang) or (ly nang)) dai hoi. ((hieu ve) OR (hieu van)) cao duc minh anh hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: thuat lanh ((y nang) or (ly nang)) dai hoi. ((hieu ve) OR (hieu van)) cao duc minh anh hai cua tre*.
