In particular we have to retrieve the documents with a normal search followed by a result reranking phase where we calculate the cosine similarity between the retrieved documents and the user profile. > That's exactly what RankQuery can do for you.

See for example ReRankQParserPlugin. https://lucene.apache.org/solr/guide/7_2/query-re-ranking.html You can return your type of RankQuery, that will have access to the TopDocsCollector, so there you can reorder the documents by cosine similarity. https://lucene.apache.org/solr/6_6_0//solr-core/org/apache/solr/search/RankQuery.html -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
