solrj

How can I determine the total number of documents in a Solr index using Solrj? After hours of searching on my own, I actually have an answer (given below); I'm only posting this question so others can find the solution more easily. Here's what I'm using. Is this canonical? Is there a better way? SolrQuery q = new SolrQuery("*:*"); q.setRows(0); // don't actually request any data return server.query(q).getResults().getNumFound(); Your answer of sending the query : is probably the best, most general solution. Especially if you are using SolrCloud. However, there is an alternate solution, the

I use the following method to submit a document to Solr: public boolean addDocument( File doc ) throws IOException, SolrServerException { ContentStreamUpdateRequest csur = new ContentStreamUpdateRequest( "/update/extract" ); csur.addFile( doc ); csur.setParam( "literal.id", Utils.getAbsolutePath( doc ) ); csur.setAction(

I am able to read/access data from solr using solrj :-> HttpSolrServer solr = new HttpSolrServer("http://111.111.111:8983/solr/mysolr"); HttpClientUtil.setBasicAuth((DefaultHttpClient) solr.getHttpClient(), "admin", "akshaybhatt"); but it gives me I/O Exception as below. There are other examples on SO about authentication but I have no idea how do I use authentication in Solrj. The below error comes only when I try to update a record (and possibly add a record, not tested yet) org.apache.solr

I am able to get the suggestion response from Solr Admin UI, but when the same is being tried from solrj client the above exception arises.

简介 SolrJ是操作Solr的JAVA客户端，它提供了增加、修改、删除、查询Solr索引的JAVA接口。SolrJ针对 Solr提供了Rest 的HTTP接口进行了封装， SolrJ底层是通过使用httpClient中的方法来完成Solr的操作。 SolrJ/Solr 跨版本兼容性 SolrJ通常向后保持兼容性，可以使用新版本的SolrJ访问较旧的Solr,反之亦然。建议使用同Solr server同版本的SolrJ, 详见 http://wiki.apache.org/solr/Solrj 中关于兼容性的描述。 示例代码 采用 SolrInputDocument对象 增加、删除索引 import java.util.ArrayList; import java.util.Collection; import java.util.List; import org.apache.solr.client.solrj.impl.HttpSolrServer; import org.apache.solr.common.SolrInputDocument; public class AddDocsDemo { public static final String SOLR_URL = "http://172.168.63.233:8983/solr"; public static

出现这种情况是因为baseurl填写错误,最开始的时候我写的是用tomcat启动后浏览器中访问solr的地址 结果就出现了如题的异常,当然提示的是404,还有可能提示405,Method not allowed,method post is not supported等等 查看源码后发现给出的实例是这种格式 http://ip:port/solr/+core , 修改后重新测试正常 solrj 7.x Expected mime type application/octet-stream but got text/html. 原文：https://www.cnblogs.com/tele-share/p/9226783.html
