Amazon Cloudwatch Logs Insights

I have to find the results in cloud watch log insights and below are the fields in logs :

Field   Value
@ingestionTime  
1681410599635
@log    
875721534563:ftp_Logs
@logStream  
server
@message    
MDTM|13/04/2023 06:29:57 PM|[SFTP:2547246_0:abc:x.x.x.x] READ: *fileExists /abc/xyz.txt:true*
@timestamp  
1681410598624 

I tried using

fields @timestamp, @message, @logStream, @log 
| filter @message="abc"
| sort @timestamp desc
| limit 2000

but not getting any results , if can help in parsing or filtering

>Solution :

filter @message="abc" finds the logs where the entire message is literally abc and nothing else.

What you want is filter @message like "abc". See the docs.
