Not sure I understand your problem nor your code snippet.
Let's assume you have a directory $dir_arch/logs containing .gz and .Z files, all of which you want to search for 5 items in domainlist. The order of the resulting output does not seem to matter, does it? So sth. like this should do the job for you:
Code:
domainlist="4prd|5prd|6prd|7prd|8prd"
#               ^--- "or" in EREs 
gzgrep -E "$domainlist" $dir_arch/logs/*.gz >> $dir_arch/logs/$domain_$myhost.txt
#       ^--- tell grep to use ERE        ^--- run this on all gzipped files
zcat $dir_arch/logs/*.Z | grep -E "$domainlist" >> $dir_arch/logs/$domain_$myhost.txt
#                     ^--- run this on all compressed files
gzip -f $dir_arch/logs/$domain_$myhost.txt

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
