How to write this query in laravel 5

I'm experiencing difficulty in writing this query in laravel 5.1,

select * from `host_requests` where `host_id` = 5 and (`email` LIKE "%v%" or `request_url` LIKE "%v%")

The purpose of this query is to fetch records that are associated with host_id = 5, also email and request_url are optional if they set then LIKE clause should be used. I wrote the query in laravel like this

$searchname = "v";
$hostid = "5";
$data = HostRequest::where('email', 'LIKE', '%' . $searchname . '%')
                ->where('host_id', $hostid)
                ->orwhere('request_url', 'LIKE', '%' . $searchname . '%')
                ->latest('id')
                ->paginate($size);

It is fetching all the records that are also not associated with host_id = 5.

Any help is much appreciated..Thanks
