Tweaking Solr scoring function

Question

在Solr 6.0.0中，我想根据匹配的字段（在索引和搜索xml文件中）调整得分，是否必须重写自己的相似性类？

Answer 1

Although you can use a custom Similarity, that's more useful for changing things like how term popularity effects score. Simply ranking different fields differently is typically what you use score boosts for.

q=foo:something^100 OR bar:something^10

I recommend reading https://wiki.apache.org/solr/SolrRelevancyFAQ and maybe take a look at the dismax query parser, which has a convenient notation for that kind of thing. See https://cwiki.apache.org/confluence/display/solr/The+DisMax+Query+Parser (and the "qf" parameter)
