Hey there,
In order to remove photo and people from search, you need to disable 'Smart Search - EasySocial Users' and 'Smart Search - EasySocial Photos' in
Backend > Extension > Plugins.
Then go to Backend > Components > Smart Search, press 'Clear Index' then press 'Index' for reindex existing data. The reason you need to do this is because the system will check for the filter whether it has the data in the database or not, if it finds out that there is still got users and photos in the database, the People and Photo filter still will appear.
Can you give a try to see whether is it good to go for you?
