one case » some case, one class, one phase
we can't » why can't, we cannot, we don't
one can » one can't, line can, one bank
jane a » jane e, jane o, jane _
jan a » can a, jan m, jan c
sau » saur, sabu, saul

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yang ((jan a) OR (jane a)) gene ((((one can) or (one case))) or (we can't)) one sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((jan a) OR (jane a)) gene ((((one can) OR (one case))) OR (we can't)) one sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((jan a) OR (jane a)) gene ((((one can) or (one case))) or (we can't)) one sau ;".
• Adding a wildcard symbol may retrieve word variants: wang yang ((jan a) OR (jane a)) gene ((((one can) or (one case))) or (we can't)) one sau ;*.
