Improve search result ordering , giving prioity to pages that have the all the search works found closer together or as a phrase

I sometimes find the ordering of search results a little difficult to use. In particular, results which have phrases or have matches closer together are not put high enough.

An example:
On our wiki I was searching for jira time tracker; there are 2 pages that have details about this little app that we've built. The one I was looking for was on page 3 of the search (see searchResults1.png). If I search with quotes "jira time tracker" then I only get the 2 pages back (see searchResults2.png).

It would be better to prioritise this ranking of pages with phrases or matching words closer together.
