通过执行以下操作，终于使它正常工作。不知道这是否是最好的方法，但是它有效！希望对您有所帮助，如果您有任何改进或建议，请随时告诉我。
# app/models/movie.rbdef self.facets_search(params) query = params[:query].presence || "*" conditions = {} conditions[:year] = params[:year] if params[:year].present? movies = Movie.search query, where: conditions, facets: [:year], smart_facets: true, page: params[:page], suggest: true, highlight: true, per_page: 10 moviesend。
# app/controllers/movies_controller.rbdef index @movies = Movie.facets_search(params)end
。
# app/views/movies/index.html.erb<% if @movies.facets["year"]["terms"].present? %> <div> <ul> <% @movies.facets["year"]["terms"].each do |filter| %> <li><%= link_to "#{filter["term"]} (#{filter["count"]})", "/movies?year=#{filter["term"]}" %></li> <% end %> </ul> </div><% end %>
