Hello,
Has anyone implemented the new rescorer (recore top-k results) capability
using the java api? There is nothing in the documentation yet related to
that and I searched through the source code for some test examples but was
not able to find anything related to the rescorer (other than the classes
themselves). Any guidance one can provide is greatly appreciated as I am
excited to implement this given the results I have observed so far using
the REST API and the rescorer.
Thanks!

for anyone that is using phrase based queries today, I HIGHLY recommend you check out the "rescorer" capability in 0.90, it totally rocks!!! The performance lift it provides is dramatic to say the least.
Good work ES Team!
