Retrieving the relevant search from search file in the main file

I have two files:
file 1:

Code:
hello.com    neo.com,japan.com,example.com
news.net    xyz.com, telecom.net, highlands.net, software.com
example2.com    earth.net, abc.gov.uk

file 2:
Code:
neo.com
example.com
abc.gov.uk

file 2 are the search keys to search in file 1 if any of the search key is found in file 1 it should return the row with the found search key else just the row of the file 1 like this:

Code:
hello.com    neo.com, example.com
news.net
example2.com    abc.gov.uk

I tried this:
Code:
awk 'NR==FNR{a[NR]=$0;next}      {l=$1;for(x in a)if($0~a[x]){l=$0;break}print l}' file2 file1

it gave me the result like this:
Code:
hello.com   neo.com,japan.com,example.com 
news.net 
example2.com    earth.net, abc.gov.uk

Any idea to fix this since ? file 1 is very huge like 2 GB what can be efficient way to write this ?

Locale::Language(3)					User Contributed Perl Documentation				       Locale::Language(3)

NAME
Locale::Language - standard codes for language identification SYNOPSIS
use Locale::Language; $lang = code2language('en'); # $lang gets 'English' $code = language2code('French'); # $code gets 'fr' @codes = all_language_codes(); @names = all_language_names(); DESCRIPTION
The "Locale::Language" module provides access to standard codes used for identifying languages, such as those as defined in ISO 639. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639 two- letter codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying languages. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lang = code2language('en','alpha-2'); $lang = code2language('en',LOCALE_LANG_ALPHA_2); The codesets currently supported are: alpha-2, LOCALE_LANG_ALPHA_2 This is the set of two-letter (lowercase) codes from ISO 639-1, such as 'he' for Hebrew. It also includes additions to this set included in the IANA language registry. This is the default code set. alpha-3, LOCALE_LANG_ALPHA_3 This is the set of three-letter (lowercase) bibliographic codes from ISO 639-2 and 639-5, such as 'heb' for Hebrew. It also includes additions to this set included in the IANA language registry. term, LOCALE_LANG_TERM This is the set of three-letter (lowercase) terminologic codes from ISO 639. ROUTINES
