Hi,

I have a simple issue. I'm trying to create to my custom rescorer plugin and I've started with this elasticsearch out of the box example: [https://github.com/elastic/elasticsearch/blob/master/plugins/examples/rescore/src/main/java/org/elasticsearch/example/rescore/ExampleRescoreBuilder.java](https://github.com/elastic/elasticsearch/blob/master/plugins/examples/rescore/src/main/java/org/elasticsearch/example/rescore/ExampleRescoreBuilder.java)

I can successfully install my plugin in the elasticsearch, after that I'm starting elasticsearch client in the debug mode with the following command:

> ES\_JAVA\_OPTS="-Xdebug -Xrunjdwp:server=y,transport=dt\_socket,address=4000,suspend=y" ./elasticsearch

and I can successfully connect my debugger to the elasticsearch client and I can see that I'm hitting breakpoint inside my overriden method:

> public List\<RescorerSpec\<?\>\> getRescorers()

After that I'm trying to send request that will hit breakpoint in the rescore method. Here's the request (I took it from elasticsearch docs):

`POST /_search { "query" : { "match" : { "text" : { "operator" : "or", "query" : "The quick brown" } } }, "rescore" : { "window_size" : 50, "query" : { "rescore_query" : { "match_phrase" : { "text" : { "query" : "The quick brown", "slop" : 2 } } }, "query_weight" : 0.7, "rescore_query_weight" : 1.2 } } }`

but have no luck.
