Umbraco Version: 10.1.0
When I try to save/publish or perform a search in umbraco bacoffice, I receive this error message:
Lucene.Net.Index.CorruptIndexException: invalid deletion count: 2 vs docCount=1 (resource: BufferedChecksumIndexInput(SimpleFSIndexInput(path=“C:\home\site\wwwroot\umbraco\Data\TEMP\ExamineIndexes\InternalIndex\segments_1tk”)))

I have followed the temporary solution to fix the corrupted index by deleting the /temp/examineindex folder and then restart which fixes this issue.
Is there any way to prevent this issue and what is causing it in the first place?
