If you are trying to use Boolean operators, they must be ALL CAPS: (("zeng" OR "feng") OR ("peng" OR "pen")).
The words AND, OR and NOT may confuse the search; try adding quotes: "((\"zeng\" or \"feng\") or (\"peng\" OR \"pen\"))".
Removing quotes may allow a broader search: (( zeng or feng ) or ( peng OR pen )).
Adding a wildcard symbol may retrieve word variants: (("zeng" or "feng") or ("peng" OR "pen"))*.
