Cross-domain search?

Hi! ElasticPress already has that feature. You can search through your sites adding a sites parameter in the args passed to WP_Query. More in our docs: https://10up.github.io/ElasticPress/tutorial-indexables.html (this is only available if you have ElasticPress enabled for the entire network.)

As we don’t provide support here, please ask any following up question in our GitHub repository. As all the next steps will happen on GitHub, I’m marking the topic as resolved now. Thanks!
