Hello. I have 2 instances and index with 3 shards. For my deep search im using search after. Search after uses doc id of document as sort parameter, with the following options "\_source":false , stored\_fields":["_none_"] . After performing deep search I don't always get the same result size (In dev console for total its says 600k results im getting 570k 580k 590k ...) Note: For doc id I set unique id (not using the default one by elastic) Even with PIT I have the issue but its more precise then without. Based on documentation it should be the best solution. Do we have any diagram or explanation how ES stores a search data in this example. But, If I use for sort a unique property from my document (for example productID) it returns for the same request always the same results size and all results ... Note: I don't have issue on 1 instance, only for 2. Version 8.3.3 ---
