Multiple domain restriction

I want to search multiple domains. Can I use q=query site:reddit.com with a sites parameter? How do I format the query?

Looking for that as well. I tried “query site:domain1.com OR site:domain2.com” but that did not work. Is there an undocumented syntax we are missing?

I have tried this by using the site operator in my query but I get results from domains outside of my domains joined by the OR operator.
