I have been able to get legacy search to work for both the opportunities and contacts module, but not for businesses.
I have used the below code, but both options do not work.

‘enable_legacy_search’ =>
array (
0 => ‘Contacts’,
1 => ‘Opportunities’,
2 => ‘Businesses’,
),
$sugar_config[‘enable_legacy_search’][] = ‘Contacts’;
$sugar_config[‘enable_legacy_search’][] = ‘Opportunities’;
$sugar_config[‘enable_legacy_search’][] = ‘Businesses’;
