如何在Lucene/Solr中为术语查询分配权重 [英] How to assign a weight to a term query in Lucene/Solr

问题描述

我正在以编程方式构造BoostedQuery，并且正在创建两个TermQuery实例，这些实例将添加到BoostedQuery实例中:

I am programatically constructing a BoostedQuery and I am creating two TermQuery instances which will be added to BoostedQuery instance:

Query query1 = new TermQuery(new Term("body", "new"));
Query query2 = new TermQuery(new Term("body", "york"));

但是我想知道是否可以像在Solr的qf字段中那样增加一些权重.这是一个示例:

But I am wondering if I could add some weight to this like I can do in qf field in Solr. Here is an example:

body:new^0.1
body:york^0.1

任何帮助或指针将不胜感激.

Any help or a pointer would be appreciated.

推荐答案

或者在解析的查询中，完全按照您在问题中指定的方式使用StandardQueryParser:

Or in a parsed query, using StandardQueryParser, precisely as you specified in your question:

body:new^0.1
