This should work:
#!/usr/bin/perl -w
use strict;
my @users = ("Andrew", "Andrews", "Eric", "Andy", "Test");
my $param = "AnDr"; # what to search for
foreach (@users) {
print "$_\n" if /$param/i;
}
__OUTPUT__
Andrew
Andrews
Update: Check the references that were mentioned in the above post. You need to read up on the m// operator. Also check this post for a list of some of the modifiers.
Update2: Your thread title was "Search and Replace. After you match the username to the search pattern, if you are wanting to replace it, you should also look into the s/// operator.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
