Currently what I know is def search_data { a:a, b:b, c:c, } end 回答1: Per the docs: By default, all records are indexed. To control which records are indexed, use the should_index? method together with the search_import scope. This should work for your case: class People < ApplicationRecord searchkick # you probably already have this
