I modified the query to be more complex so that relevancy is considered.

Browse source 
Features of the query are below in order of importance(weight):

1) Phrase Match on Name
2) Term Match on Name
3) Contains Term on Name
4) Phrase Match on Author,Title,Description
5) Term Match on Author,Title,Description
6) Contains Term on Author,Title,Description
