Are you asking to sort on the number of matching terms?
Not an answer, but hopefully giving you pointers...
Firstly, highlighting is done in the highlighting component, which comes
after the QueryComponent in the list of search components invoked.
Sorting happens within the QueryComponent, which therefore cannot make
use of information not yet derived, which makes your request challenging
right from the start.
A sensible way to implement sort here is to implement a function query
(which I think you can do using a ValueSourceParser in 4.0). You can
then sort on that function. So, the question is how can you derive a
numerical value from a document that will represent your sort
preference, before highlighting has actually happened, and how can you
do so quickly enough, given that the value will have to be calculated
for every document matching your query, not just for the ones returned
to your user.
