I am having trouble finding a recommended approach for the location of a search center in a SharePoint implementation with multiple site collections
I am using SharePoint 2013's best practice of using one web application and multiple host named sit collections within it.
I have an intranet site collection, teams site collection, a site collection for projects and one for my sites. The URLs will be intranet.domain.com, teams.domain.com, projects.domain.com and people.domain.com
Where should the location of a search center to search all content sit? I have considered creating another site collection to host it, or creating a search center in each site collection.
Any feedback on these approaches or perhaps another approach would be great!
