Thanks Erick and everyone.We are checking on stats cache. I noticed stats skew again and optimized the index to correct the same.As per the documents.
https://lucidworks.com/2017/10/13/segment-merging-deleted-documents-optimize-may-bad/ and https://lucidworks.com/2018/06/20/solr-and-optimizing-your-index-take-ii/ wanted to check on below points considering we want stats skew to be corrected. 1.When optimized single segment won't be natural merged easily.As we might be doing manual optimize every time,what I visualize is at a certain point in future we might be having a single large segment.What impact this large segment is going to have? Our index ~30k documents i.e files with content(Segment size <1Gb as of now) 1.Do you recommend going for optimize in these situations?Probably it will be done only when stats skew.Is it safe?
