Answer 1

if you want to compare result start with input character then remove % from beginning
$sql = "SELECT * FROM submission where keyword like '".$term."%' or companyname
like '".$term."%' ORDER BY CASE WHEN keyword LIKE '".$term."%' THEN 1
ELSE 2 END";

Answer 2

You used %$term% in your query. So whether the data store the searched keyword anywhere in the string, it will display to you. So if you want to search the data start with a specific character remove % from the start of your query to make it as $term% as
$sql = "SELECT * FROM submission where keyword like '".$term."%' or companyname
like '".$term."%' ORDER BY CASE WHEN keyword LIKE '".$term."%' THEN 1
ELSE 2 END";
