Jobs may be filtered to select only builds matching particular parameters or other build variables. Use PARAM=VALUE,... to list the parameter filter; this is the same syntax as described for multiconfiguration jobs in Project name except with parameters instead of axis values. For example, FOO=bar,BAZ=true examines only builds that ran with parameter FOO set to bar and the checkbox for BAZ was checked.

You shoudn't use "Build selector for Copy Artifact" parameters here, as it doesn't preserve compatibility when you upgrade plugins, and doesn't work for builds built before upgrading.
