When we indexing I see the deleted docs are a bit changing.. I was surprised when developer reindex 120M index, we had around 110M of deleted docs and this number was not falling. As you wrote, the typical behavior should be merging deleted docs to 10-20% of whole index? So it should be after two weeks around 20M of deleted docs.
I'm not sure of settings in our solrconfig.xml: <mergePolicy class="org.apache.lucene.index.TieredMergePolicy"> <int name="maxMergeAtOnce">10</int> <int name="segmentsPerTier">10</int> </mergePolicy> <mergeFactor>10</mergeFactor> <mergeScheduler class="org.apache.lucene.index.ConcurrentMergeScheduler"/> Should we change some of them? The mergeScheduler class is empty. When I go to Core Admin, select our core I see: maxCacheMB=48.0 maxMergeSizeMB=4.0 Is that ok, or the values are too low?
