[syslog-ng] Two or more conditions on a action

Hi all, Is it possible to configure two or more conditions under an action?? For example: <action trigger="match" condition=" '${first_field}@1' == 'something_1' & '${second_field}' == 'something_2' "> This action it doesn't works ... I am using syslog-ng 3.3.5 Thanks.
