The result of Query all will change all the time?

[zhenyuan wei]

Hi all,
I indexed 49999810 documentsand make some kill processes tests.
After all indexed done, I query all many time, and found the numFound is
not the same number. OutPut Example:

"responseHeader":{ "zkConnected":true, "status":0, "QTime":8, "params":{ "q
":"*:*", "_":"1544171213624"}}, "response":{"numFound":49941265,"start":0,"
maxScore":1.0,"docs":[
。。。

。。。
"response":{"numFound":49934265,"start":0,"maxScore":1.0,"docs":[
。。。
"response":{"numFound":49875720,"start":0,"maxScore":1.0,"docs":[


background:
solr 7.3.1 on HDFS 2.7.2
mycollection with 4 shards, rf=2
when indexing, I kill solr/hadoop data node, then wait for indexing job
finish.
finally, I found query will change all the time, like above output
examples.
