Thanks for explaining more.

The regular expression seems rather complex (In other words, I couldn't figure it out Smilie), so I tried a different way.

Instead of making one all-purpose, confusing pattern, I suggest to to let find use either of two patterns. See if this makes sense, and does the job:
Code:
$ cat temp.sh
touch exploitation_ora.log.2013-03-28.001
touch server.log.2013-03-28.tar.gz

date=2013-03-28
instance=ora

for type in exploitation server; do
  echo Looking just for type = $type
  find . \( -name "${type}_$instance.log.$date.*" -o \
            -name "${type}.log.$date.*" \) -print
  echo
done

echo Looking for type = exploitation OR server
find . \( -name "exploitation_$instance.log.$date.*" -o \
          -name "server.log.$date.*" \) -print

Code:
$ ./temp.sh
Looking just for type = exploitation
./exploitation_ora.log.2013-03-28.001

Looking just for type = server
./server.log.2013-03-28.tar.gz

Looking for type = exploitation OR server
./exploitation_ora.log.2013-03-28.001
./server.log.2013-03-28.tar.gz

So the final find command would be the one to use, unless there is some other complication I'm missing.

DOVEADM-LOG(1)							      Dovecot							    DOVEADM-LOG(1)

NAME
doveadm-log - Locate, test or reopen Dovecot's log files SYNOPSIS
doveadm [-Dv] log errors [-s min_timestamp] doveadm [-Dv] log find [directory] doveadm [-Dv] log reopen doveadm [-Dv] log test DESCRIPTION
The doveadm log commands are used to locate and reopen the log files of dovecot(1). It's also possible to test the configured targets of the *log_path settings. OPTIONS
Global doveadm(1) options: -D Enables verbosity and debug messages. -v Enables verbosity, including progress counter. COMMANDS
log errors doveadm log errors [-s min_timestamp] The log errors command is used to show the last - up to 1,000 - errors and warnings. If no output is generated, no errors have occurred since the last start. -s min_timestamp An integer value, representing seconds since the epoch - also known as Unix timestamp. When a min_timestamp was given, doveadm(1) will only show errors occurred since that point in time. log find doveadm log find [directory] The log find command is used to show the location of the log files, to which dovecot(1) sends its log messages. If dovecot(1) logs its messages through syslogd(8) and doveadm(1) could not find any log files, you can specify the directory where your syslogd writes its log files. log reopen doveadm log reopen This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings. These settings are configured in /etc/dovecot/conf.d/10-logging.conf. This is for example useful after manually rotating the log files. log test doveadm log test This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files. The used prior- ities are: debug, info, warning, error and fatal. EXAMPLE
This example shows how to locate the log files used by dovecot(1). doveadm log find Looking for log files from /var/log Debug: /var/log/dovecot.debug Info: /var/log/mail.log Warning: /var/log/mail.log Error: /var/log/mail.log Fatal: /var/log/mail.log REPORTING BUGS
Report bugs, including doveconf -n output, to the Dovecot Mailing List <dovecot@dovecot.org>. Information about reporting bugs is avail- able at: http://dovecot.org/bugreport.html SEE ALSO
