I had overlooked that a user can have more than one connection, see this: 

use strict;
use warnings;
use Data::Dumper;

my %users;
my %searches;

#open my $fh, '<', 'file1.txt' or die "failed: $!";
while (<DATA>) { # I use DATA handle instead of $fh for convenience
        if( /BIND/ ) {
                my( $conn, $uid ) = /conn=(\d+).*uid=(.*?),/;
                push @{$users{$uid}}, $conn;
        }
        if( /SRCH=Q/ ) {
                my ($timestamp, $conn) = /\[(.*?)\] conn=(\d+)/;
                push @{$searches{$conn}}, $timestamp;
        }
}
#close $fh;

for my $user (keys %users) {
        for my $conn (@{$users{$user}}) {
                print "User $user had ".scalar( @{$searches{$conn}} ).
+" searches on connection $conn\n";
                print "\t=> Bad user!\n" if  @{$searches{$conn}} > 3;
        }
}

print Dumper \%users;
print Dumper \%searches;
