sts human » its human, sdgs human, vs human
gene lang » gene bank
yang ka » yang fan, yang yao
yang xi » yang di, yang jui
yang yi » yang di, yang jui

young 5 » young _, young 4, young a
lang 3 » klang 3, gang 3, lang _

• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang ka) OR (((yang xi) OR (yang yi))))hg sts human gene lang 3 ((young 6) OR (young 5)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang ka) OR (((yang xi) OR (yang yi))))hg sts human gene lang 3 ((young 6) OR (young 5)) ;*.
