Hi Steven, When scores produce a tie, internal Lucene document IDs are used to break it. However, internal Lucene Ids can change when index changes. (merges, updates etc).
You can see those values with [docid] - DocIdAugmenterFactory. If you want 100% stable sorting, use a second sorting criterion. e.g. sort = score desc, some_field asc Ahmet On Monday, August 24, 2015 4:56 PM, Steven White <swhite4...@gmail.com> wrote: Hi Everyone, When I search for a term in Solr, and it happens that 10 doc end up with the same score, what's the order of doc ranking in the set of those 10 equally scored doc and what is it based on? Is there a link I can read more about this? Thanks, Steve
