Order search results by title relevance

[keesiemeijer]

The search results should be ordered by title first. As it is now you get a mixed bag of content and title matches.
If it's ordered by title you get more specific results similar to the search query.

See the screenshots for "get posts"

Set orderby for searches with pre_get_posts to 'search_orderby_title'

To get even more relevant results the order should be to show the shortest match first. To get the same results for sentence matches, spaces should be converted to underscores in the posts_orderby clause.
