标签： solr scoring

我们正在尝试评估Solr作为搜索解决方案并面临检索分数的问题。我们进行了抓取和索引，但所有得分都是0.0，尽管根据我们的知识，我们没有更改任何关于得分的配置。

如果有人可以复制并让我们知道原因，那将会很棒。会有很大的帮助。

答案 2 :(得分：0)

我的过滤器中有www.mcdonalds.ca域配置。由于这被重定向到www.mcdonalds.ca.ca/en.html，因此任何网址都没有得分。

我修改了顶部网址而不是www.mcdonalds.ca，我确实提到了www.mcdonalds.ca/ca/en.html并且它有效。

请仔细阅读以下网址 -
