   Thanks @benwtrent!
   
   > One thing that still bugs me is attaching yet another parameter to a 
common method. Especially a parameter that will be rarely used (my gut reaction 
is choosing the correct seed query is difficult and average users will never 
use it). I will think more about this. Maybe its just fine and I am 
overreacting.
   
   That's a fair point. What might be the alternative that doesn't affect the 
main `LeafReader.searchNearestVectors` methods? Perhaps a private member with a 
getter/setter?
   
   > I like this idea. Do you have any scripts & test data where you have 
tested that this Lucene implementation works and gives as good as results as 
you had in the original paper?
   
   I've tested it on some internal datasets and it's performed favorably, 
albeit not quite as strong as the original paper. (This is likely due to both 
differences in the distribution of the data and implementation differences, 
especially around the efficiency of lexical search.) Automated tests in the 
suite test that it's functioning as expected.
