随机化搜索结果

Question

我使用Searchkick搜索用户记录。我每次都得到相同的结果订单。我已经阅读了文档但找不到任何内容。以下是我正在使用的实现。

search_params = {}
search_params[:where] = where     #where holds all the conditions for the search
search_params[:order] = {user_id: :desc}
user_matches = User.search "*", search_params

Answer 1

铁路方式：

user_matches.results.shuffle

Searchkick方式：

seed = current_user.id
# setting seed to the user_id will make the random results consistent for that user...
# ... if you always want random results than you should make seed = Time.zone.now.to_i
User.search( "*", body: {query: {function_score: {random_score: {seed: seed}}}} )

对于searchkick方式，这里是elasticsearch reference
