When I want to limit search results on Google, I need to use the site operator multiple times, like this:
-site:gov.br -site:ebc.com.br -site:sintep.org.br -site:sinteal.org.br -site:cnte.org.br
It would be less verbose, and, as such, would allow me to inform more URLs, if I could do something else, like this:
-site: {gov.br; ebc.com.br; sintep.org.br; sinteal.org.br; cnte.org.br}
So: is it possible to somehow inform more than one URL per site operator?
