Combine two searches

[qysplunk]

Hi, I have 2 sample logs and I need to combine them into 1 query to grab the "Accesses" values,

Due to the log format differences, I have combined 2 different queries using append/sub-search. However I noticed, the subquery results will shows up in the "CE" field, but does not show up in "TC" field .

Or is there another way I can do to capture the Accesses value of these 2 log?

index=nginx (("SourceName=Microsoft Windows security auditing" AND EventCode=4663 AND "Message=An attempt was made to access an object" AND Object_Name="C:\\Program Files\\nginx-1.18.0\\conf\\*.conf" AND ("Accesses:*")) OR (SourceName=Microsoft-Windows-TerminalServices-LocalSessionManager AND EventCode=21))
| eval Date = strftime(_time, "%Y-%d-%m")
| eval Hostname = upper(host)
| eval Date = strftime(_time, "%Y-%d-%m")
| eval Time = strftime(_time, "%Y-%d-%m %H:%M:%S")
| rex field=Message "Accesses:\s+(?P<Action>[^<]+)"\s+Access
| append
[ search index=nginx ((EventCode=4656 Object_Name="C:\\Program Files\\nginx-1.18.0\\conf\\*.conf" Process_Name=C:\\Windows\\explorer.exe) OR (SourceName=Microsoft-Windows-TerminalServices-LocalSessionManager AND EventCode=21))
| rex field=Message max_match=0 "Accesses:\s+(?P<Action>[^>]+)"\s+Access\sReasons]
| rex field=Action mode=sed "s/\s{2,}/\n/g"
| strcat Action "-> " Object_Name CE
| eval TC = mvzip(Time,'CE')
| stats values(TC) as TC latest(Source_Network_Address) as "IP Address" by Date index Hostname
| where isnotnull(TC)
| mvexpand TC
| makemv TC delim=","
| eval Time=mvindex(TC, 0)
| eval "Events"=mvindex(TC, 1)
| fields Time Events Hostname "IP Address"
| where Events' != "-> "

Thank you
