Question regarding label configuration

[tooomm]

From the usage examples in README:

# Only issues or pull requests with all of these labels are check if stale. Defaults to `[]` (disabled)
onlyLabels:

Does this really mean, that if I put [bug,feature] there, it will only close issues that have both labels applied?
I can not put a list of labels which only one of needs to be matched?

I feel like that would narrow down the possibilities a lot!
