title: Magento 2 order the simple search by name, not relevance
body: <p>I have a project (Magento 2 site) where one of the requirements is to order the results of the search (using the search box in the top banner) by product name instead of the default 'relevance'. This doesn't appear to be as easy as changing the sort parameters for a category search which has configuration options in the XML files for that.
  I've dug down into the search code but so far any attempts at altering the locations where 'relevance' is specified have resulted in no search results at all.</p>
  
  <p>Any one know how to achieve this?</p>
