kin keong » king kong, min jeong
jing tan » wing tan, liang tan, hong tan
gene set » gene sets, game set, gene we
ein kern » einem kern, im kern, ii kern
li gene » i gene, l1 gene, iii gene

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((jing tan) OR (jing fang)) li gene set ((kin keong) OR (ein kern)) nga ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((jing tan) OR (jing fang)) li gene set ((kin keong) or (ein kern)) nga ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((jing tan) OR (jing fang)) li gene set ((kin keong) or (ein kern)) nga ;*.
