Is there any way to use Algolia to index and create a search for sites on a Wordpress Multisite installation?
E.g. so if I was browsing a site in the multisite network, then I could use a searchbox hosted on that site to search for other relevant sites in the multisite network that matched my query.
The plugin will scope the results per website. There is currently no way of easily creating a "global search" feature. When in a multi website environment you should make sure you change the index prefix per website.
We have an open issue here https://github.com/algolia/algoliasearch-wordpress/issues/415 feel free to discuss your use case there.
It looks like Elasticsearch and the plugin ElasticPress is able to do this - look for the sites parameter in the ElasticPress documentation.
