Global search and Global post issue

Global posts feed, and global site search are no producing any results even though posts are there and known words are being searched for. I am wondering if this has anything to do with it, and if you have any suggestions.

I have several sub sites. However when I look hover over "My Sites" , I only get the option for network admin my primary domain. This is also the case when I click on "My Sites" The main domain is the only option.
However when you Hover over My Sites > Network Admin > Sites all of my sub sites are there. Any suggestions?
