The rex command is for extracting fields using regular expressions.  What fields do you need to extract from those events?

If you just need to find events with either of those strings then you don't need rex at all.  Just put the strings in your base search.

index=foo ( "appl has successfully completed all authentication flows." OR "Login complete" )

Hi @richgalloway , I need to do field extra action for those 2 strings which i mentioned.

That's why I asked for rex

Field 1: appl has successfully completed all authentication flows (field name as success_logins)

Field2: Login complete"  (field name as complete_logins)

| rex "(?<success_logins>appl has successfully completed all authentication flows.)"
| rex "(?<complete_logins>Login complete)"
