On another note, LTR with reRankDocs>page_size seems to create issue. For example, Say my page_size=24 and reRankDocs=48. For first query with start=0, it returns 24 reranked results from top 2 result pages. Say, if an item (Y) from second page is moved to first page after re-ranking, while an item (X) from first page is moved away from the first page. For second query with start=24, reRankDocs=48, it returns me second page of results from results between second and third page that does not have item X. So eventually, I do not see item X from first page or next page of results. Is n't it? How do we solve this? ----- --Ilay -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
