I have just found out that pages and items (docx. ppt.) are showing in our global sharepoint environment, when using the search box and selecting "everything". This is showing results across multiple site collections.
I am the administrator for my site collection only. It is only accessible to certain people within the organisation, but I need to ensure that sensitive documents and pages cannot be searched through global search.
How can I stop anything from within my site collection from being indexed by global search?
I also am developing an internal staff knowledgebase and would like for the search function to still work for this. I'd assume that as it is searching internally for pages on a single site only, that it may still work as normal?
