I have an object in the Elasticsearch index that has a nested object which  
is a list of strings.  
I would like to do the intersection against this list in both exact and  
fuzzy ways.  
So for example I have browser names with versions in the index like:  
"browsers": [{"name":"Chrome 38"}, {"name":"Firefox 32"}, {"name":"Safari  
5"}]

the request could be:  
[{"name":"Chrome 38"}, {"name":"IE 10"}]  
then I have just 1 exact match.

or another example:  
[{"name":"Chrome 39"}, {"name":"Firefox 33"}, {"name":"Safari 5"]  
here I have 2 fuzzy-matches(Levenstein=2) and 1 exact match

Those results which have more matches should be on top.  
How would you write this kind of query ?
