Hello everyone. We recently upgraded the online version from Solr 7 to 8.11, we found a very strange problem.
Before upgrade, we wrote a row of data, the id is uniqueKey. id=1, name=alice, age=10 After upgrade, we write three rows of data and id=2 is repeated. id=1, name=alice2, age=11 id=2, name=nick, age=30 id=2, name=nick2, age=31 We found NumFound=2 when querying with debugQuery=true&q=id:1, and NumFound=1 when querying with debugQuery=true&q=id:3 For historical data, the default 'overwrite' is false? Thanks.
