Scoring of solr multivalued field

由 血红的双手。 提交于 2019-12-17 23:26:11
问题 If I have a document with a multivalued field in Solr are the multiple values scored independently or just concatenated and scored as one big field? I'm hoping they're scored independently. Here's an example of what I mean: I have a document with a field for a person's name, where there may be multiple names for the same person. The names are all different (very different in some cases) but they all are the same person/document. Person 1: David Bowie, David Robert Jones, Ziggy Stardust, Thin

由 白昼怎懂夜的黑 提交于 2019-12-17 22:35:46
问题 I am running a Solr instance on Jetty and when I search using the Solr admin panel, it returns the entire document. What should I do to get only specified fields from each Solr document returned by the search? 回答1: /?q=query&fl=field1,field2,field3 回答2: From the Solr Admin home page, click on "Full Interface". On that page there is a box called "Fields to Return". You can list the you want here (comma-separated). "*" means all fields. 回答3: http://xx.xxx.xx.xx:8983/solr/corename/select?indent

一步一步学solr：tomcat7+solr4.9环境搭建

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> solr下载地址： http://www.apache.org/dyn/closer.cgi/lucene/solr/4.9.0 tomcat下载地址： http://tomcat.apache.org/download-70.cgi 首先 将下载好的2个包解压，我在E:/test文件夹 一个空的tomcat 找到你解压好的solr4.9.0目录， 将E:\solr-4.9.0\example\webapps的 solr.war 拷贝到E:\test\tomcat7\webapps下 然后启动tomcat，这时候会报错，我们的目的是吧solr.war解压出来，等tomcat启动完成后关闭它。 建立一个solr_home，他不是我们解压出来的solr4.9.0，因为暂时用不到那么多的对象，solr_home我创建在E:\test\solr_home文件夹。将E:\solr-4.9.0\example\solr文件夹下的所有文件复制到 E:\test\solr_home里。 配置tomcat中的项目找到solr_home，这里有很多种配置，我的方法是修改E:\test\tomcat7\webapps\solr\WEB-INF下的web.xml。 将 <env-entry> <env-entry-name>solr
