The way I found to change the ranking function is by setting the similarity
property of text fields in schema.xml as follows:
`<similarity class="solr.LMDirichletSimilarityFactory"/>`
However, this means we can only set the similarity/ranking function only in
indexing time. As Solr is built over Lucene which allows changing the ranking
function in search time, I find it not logical that Solr doesn’t support it, so
it seems I’m missing something here!
That setting will change the similarity used for both index and query.
I am not aware of any way in Solr to specify a different similarity for
index than what is used for query. It wouldn't surprise me to learn
that this is possible when writing Lucene code directly.
