With BM25 we can resume work to include pageviews in fulltext search.
Previous evaluations showed that it's possible to do fine tuning with BM25 and a weighted sum.
Most of the work is already done, it's just a config change. I think I've lost the rescore settings I've used to evaluate the weighted sum but it should not be too hard to do it again. I was just a new rescore function chain with the satu function score. The duplicated task that was merged in this one should contain some info about the weights I used for enwiki.
