Answer 1

To perform a case-insensitive search using @Cyril's method for rails4-autocomplete, I did a slight modification to the named scope @DGM provided

 scope :search_by_name, lambda { |q|
   q.downcase!
   (q ? where(["lower(first_name) LIKE ? or lower(last_name) LIKE ? or concat(lower(first_name), ' ', lower(last_name)) like ?", '%'+ q + '%', '%'+ q + '%','%'+ q + '%' ])  : {})
 }

This converts the record's entry to lowercase and also converts the search string to lowercase as it does the comparison
