Apache Solr what does cat:iphone^2 name:iphone^2 mean?
我正在阅读“apache solr 搜索模式”一书，有疑问：

^2 和 ^3 是什么意思？
这意味着如果在这些字段中找到这些字词，则将其提高 2 倍或 3 倍。语法是 field:term^<weight>。请参阅参考指南中的 Boosting a term with ^。
Lucene/Solr provides the relevance level of matching documents based
on the terms found. To boost a term use the caret symbol ^ with a
boost factor (a number) at the end of the term you are searching. The
higher the boost factor, the more relevant the term will be.
Boosting allows you to control the relevance of a document by boosting
its term. For example, if you are searching for jakarta apache and you want the term jakarta to be more relevant,
you can boost it by adding the ^ symbol along with the boost factor
immediately after the term. For example, you could type:
jakarta^4 apache
将 qf 与 edismax 一起使用时，它会将相同的规则应用于这些字段中的任何命中。
The qf parameter introduces a list of fields, each of which is
assigned a boost factor to increase or decrease that particular
field’s importance in the query. For example, the query below:
qf=fieldOne^2.3 fieldTwo fieldThree^0.4
assigns fieldOne a boost of 2.3, leaves fieldTwo with the default
boost (because no boost factor is specified), and fieldThree a boost
of 0.4. These boost factors make matches in fieldOne much more
significant than matches in fieldTwo, which in turn are much more
significant than matches in fieldThree.
