Ruby on rails 太阳黑子Solr：如何通过热门领域提升

我在Solr中添加了一个“流行度”字段作为外部字段

“/solr/configsets/sunspot/conf/schema.xml”

---

通过在搜索参数中添加：boost解决了上述问题，如下所示：

Item.solr_search do
  fulltext self.q do
    phrase_fields full_title:    16.0 # pf: full_title_text^16.0
    phrase_slop 1

    boost_fields ean:            8.0  # qf: ean_text^8.0
    boost_fields author_names:   2.0  # qf: author_names_text^2.0
    boost_fields publisher_name: 2.0  # qf: publisher_name_text^2.0
  end

  adjust_solr_params do |params|
    params[:boost] = "popularity_score"
  end
end

结束
