基于Solr规则的提升

首先，您应该使用
dismax
or
edismax
query parser instead of the default
(lucene).

然后，您可以使用不同的参数来提高相关性：

1. : Use qf to boost your product_name field.
2. : Use pf to boost your product_name field where all of the terms in the q parameter appear in close proximity.
3. : Use bq to boost documents where the words

   with

   or

   without

   don’t appear. See here. For example :

   bq=(*:* -with -without)^999
