• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling ((tan chia) or (than china)) dan yang kia ((hong hai) OR (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling ((tan chia) or (than china)) dan yang kia ((hong hai) OR (zhong tai)) ;*.
