You could either create a regular expression to match both parts at the same time, or alternatively use the Perl grep function to match the username and userid individually.

Using the following data file (phonebook.txt): 

Jon:1:0123456789
Rob 1 0987654321
Sean 4 075312468
Tom-3-0111 222 333
Colin 3 0222 111 5555

You could write something like 
#! /usr/bin/perl
 
my ($username,$userid) = @ARGV;
undef @ARGV;
my @phonebook = (<>);
 
@phonebook = grep /\b$username\b/ , @phonebook;
@phonebook = grep /\b$userid\b/   , @phonebook;
 
print foreach(@phonebook);

Then if you type 
cat phonebook.txt | match.pl Jon 1

You will get Jon:1:0123456789 Hope this helps,

Update:
I do realise that the above code still has bugs, I'm just trying to give our brother Monk some pointers. For a more robust solution, you should really define a file format (e.g. colon-sperated values), then you could use split to ensure you are only matching against the right fields.
