solr与.net系列课程(五)solrnet的使用最近因项目比较忙,所以这篇文章出的比较晚,离上一篇文章已经有半个月的时间了,这节课我们来学下一下solr的.net客户端solrnet 出处 https://github.com/mausch/SolrNet 上一篇文章讲述了C#是如何请求和接受solr的数据的,请求链接是自己拼接的,接受数据是使用数据契约,solrnet就是把这些步骤封装起来,大家直接调用方法就可以请求和接受数据首先要下载solrnet所要使用的DLL Microsoft.Practices.ServiceLocation.dll SolrNet.dll HttpWebAdapters.dll 下载地址 http://pan.baidu.com/s/1pJt7Wr5 创建一个项目,然后引用上面的DLL 好了,下面就开始实战, 我们来设计一个查询条件 title="关键字" and (area="北京" or area="上海") and industry="电力" and columns="项目" order time desc (1)创建一个接收数据的实体类,内容如下 using System; using System.Collections.Generic; using System.Linq; using System.Web; using

　　上一篇已经讲到了Solr 查询的相关的参数。这里在讲讲C#是如何通过客户端请求和接受solr服务器的数据, 这里推荐使用SolrNet，主要是：SolrNet使用非常方便，而且用户众多，一直都在更新，感兴趣的可以加入他们的邮件群组，方便迅速了解SolrNet的最新动态。　　SorlNet源码地址： https://github.com/mausch/SolrNet 　　SolrNet使用说明文档： https://github.com/mausch/SolrNet/tree/master/Documentation 　　一、创建一个项目控制台程序，并引用SolrNet.dll。 Demo下载　　　　　　注意：SolrNet 依赖HttpWebAdapters.dll和Microsoft.Practices.ServiceLocation.dll 这两个dll 文件，所以，如果编译或者测试有问题，引用这两个dll 文件应该就ok了。　　二、在solr 的schema.xml 增加相关的Filed 字段，同时创建一个实体类，与schema.xml中的Filed 字段映射。　　 public class Product { [SolrUniqueKey( " id " )] public int id { get ; set ; } [SolrField( " name "

问题 I know I need to add the following code to change to dismax. ExtraParams = new Dictionary<string, string> { {"qt", "dismax"} } But how do I pass the "qf" values?

Even passing only the ExtraParams I get a 404 bad request. This is the logged queries Local parameters +

问题 I would like to dynamically show to the user which field matched the query that was sent to Solr. For example, if I had a document document field1: "yay" field2: "nay" dynamic_field_hurr_*: one: "yay" two: "nay" and i queried for "yay", would it be possible for me to know that yay was found in field1 and dynamic_field_hurr_one? I feel like I've been through the whole documentation, and thought I should use highlighting for this, but I can't get it to work on dynamic fields. On normal fields

Solr stops responding (or slows down to molasses)…(Solr newbie)

阅读更多关于 Solr stops responding (or slows down to molasses)…(Solr newbie)

问题 Running multi-core Solr under Tomcat 6.0 /Win 2008 Server and ASP.NET queries via SolrNet. One of the cores is huge i.e. ~25 million documents (~20 GB disk-space) and several fields. The other 3 cores are much smaller (few gigs each). After a couple of queries to the large index, Solr slows down dramatically and stops responding i.e. can't even open admin console. If I restart tomcat, things again works ok for a few more queries and then molasses to stop. I have checked the machine RAM and

SolrNet: SolrConnectionException (400) bad request when attempting to Add and Commit

阅读更多关于 SolrNet: SolrConnectionException (400) bad request when attempting to Add and Commit

问题 I have gotten to the point where SolrNet executes the "Add" method but when I try to "Commit" is when I receive the error. The following is my schema.xml, model, code calling it, and the error I get. Even stranger is that despite the error, the model is added to my Solr index AFTER I restart Tomcat (so it still adds my model despite the error but not immediately): schema.xml (fields and fieldtypes):  <field name="part_numbers" type="my_string_exact" indexed="true" stored="true"
