Here is what's wrong in the test: You have to null the writer field in BaseExplanationTestCase like the searcher in afterClass().


was (Author: thetaphi):
You have to null the writer fiel in BaseExplanationTrstCase like searcher in afterClass. It's shown how to do for the other fields there :)

> Some of the folks [reported|http://find.searchhub.org/document/80666f5c3b86ddda] that sometimes explain's score can be different than the score requested by fields parameter. Interestingly, Explain's scores would create a different ranking than the original result list. This is something users experience, but it cannot be re-produced deterministically.
