Index restored from snapshot performs differently compared to original one

(Bing Xie) #1

I run an elasticsearch on a new server and retore an index from snapshot which was created in another elasticsearch server. But I find the new es server performs different from the original server. I prepared a list of questions and search top 10 match per question from both server. The order of match questions are not the same and sometimes the match questions set from original server is not the same with the new one. I thought snapshot and restore can perfectly copy index and get the same result from both server. Something wrong during my snapshot and restore processing? Nothing changed since snapshot created.

Has anything changed in the source index since you took the snapshot? Are the document counts the same?

Nothing changed since snapshot created.
Index in both server count the same.

How many shards? How many documents? Do the indices have the same number of segments?
