Hi Joel, There also seems to be an issue related to how QueryRequest instance is created in scoreNodes implementation. It seems to be using GET method instead of POST. As a result, when underlying stream is big, scoreNodes function fails with an exception "URI is too large"
I found a related is issue mentioned here, http://lucene.472066.n3.nabble.com/Streaming-Expressions-GET-vs-POST-td4415044.html ScoreNodesStream.java initializes QueryRequest as follows. QueryRequest request = new QueryRequest(params); vs TimeSeriesStream.java which does it like this. QueryRequest request = new QueryRequest(paramsLoc, SolrRequest.METHOD.POST); Is this also a bug?
