Hi All,
We are using elk 7.17.1 with winlogbeat version 7.8 version with ECS version 1.5.
While testing out winlogbeat 8.1.0 with ECS version 8.0.0, now my lucene queries are now doing partial matches.
A simple example of Lucene query
winlog.event_data.Image:C\:\\Windows\\System32\\schtasks.exe
is doing partial matching the field winlog.event_data.Image and listing anything with C or
C:\
C:\Windows\
C:\Windows\System32\
This behavior is not seen with data in indexes with winlogbeat agent 7.8
Expected matches were where field value is C:\Windows\System32\schtasks.exe
Did I miss something here?
Thank you in advance!
