Hi, Thanks erick and shawn for the reply.
Just wanted to clarify that commit size of 10 was only an example and in production commit is handled via auto-commit feature of solr. The requirement we have is to store around 20-30 lakh docs out of which around 5-6 lakh docs get updated daily. What I have observed is though merge factor seems to work we always end up with around 6 lakh deleted docs in index daily. On optimizing all this deleted docs are removed. We benefit on memory as well as query speed on optimization. But as I understand its a small time gain and situation repeats itself daily. I fail to understand why this deleted docs are not removed from index on merging. Is there a good documentation which explains how exactly is merging done? What can I do to solve this problem other than optimization? -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-Deleted-Docs-Issue-tp4193292p4193937.html Sent from the Solr - User mailing list archive at Nabble.com.
