The fact that it is undefined if none of the checkboxes
are checked is expected behavior. Just do:
if( isset( $_POST['keyword'] ) {
}
to determine if you need to do any further processing.

if( isset( $_POST['keyword'] ) {
foreach( $_POST['keyword'] as $checkboxValue ) {
echo 'Checkbox ' . $checkboxValue . ' was checked<br>';
}
}
