Is there already a way to disable the multi-site search tab ?
Easier to explain why it's useful with an example : Say we create a set of websites dealing with a rock band tour. We have a main site that is a kind of portal for whole world, and one site by country with its own webmaster. Each webmaster adds events in his country site.
What we need : to be able to search for all events around the world when on the main world site, but only find the ones relating to the country when on a country site.
We need to share the same index, but to prevent the events from other countries to appear on a country site, we need to activate the multisite solr search module (to restrict the search to one site). However, we don't need to search across multiple sites when on a country site, so the tab is at least useless, or even undesirable if we want to prevent country users from accessing world content.
Thanks in advance,
