Hi Stian,
We have the same issue with our documents. I fixed that by setting b = 0 in
our schema for BM25 similarity.
<similarity class="solr.BM25SimilarityFactory">
<float name="b">0</float>
</similarity>
I don't know if BM25 can be used with your version of Solr. Personally I
think it's worth upgrading for.
