Hi,All:
I want to ask a question, How does Solr implements Paging, such as start = 1000000 and row = 20 I roughly saw Solr source, hare is the code: getDocListNC(QueryResult qr,QueryCommand cmd) ; often it uses : topCollector = TopFieldCollector.create(weightSort(cmd.getSort()), len, false, needScores, needScores, true); super.search(query, luceneFilter, collector); See it , it only fetch all docs and then do paging, So my question is Is it too slow? if I set len = 10000000 Often cause OOM Is Solr shard can perfectly solve it?
