Q: Every time I search on safari screen goes back to home screen

Hi Smk63bmw,

I understand that you are experiencing an issue when attempting to search with Safari. I would suggest that you try the steps in the following article to help you address this issue:

If Safari doesn't load pages from multiple sites

 In OS X Yosemite, you can delete website data for the past hour, or past few days if websites or pages stopped loading recently.

1. Choose History > Clear History and Website Data.
2. In the sheet that appears, choose the range of data you want to remove from the Clear pop-up menu.
3. Click Clear History.
   

If you want to remove website data for all of the sites and pages you've ever visited, choose "all history" from the Clear pop-up menu. The option to Remove All Website Data in the Privacy pane of Safari preferences does this, too. These options also reset your browsing history and Top Sites.

If Safari doesn't load a page or webpage items are missing - Apple Support
