solrj

I can reindex an entire solr core using the following code: public void indexSolr() throws SolrServerException, IOException { HttpSolrServer solr = new HttpSolrServer(solrIndexPath); logger.info("Indexing fcv solr at " + solrIndexPath); // reindex to pickup new articles ModifiableSolrParams params = new ModifiableSolrParams(); params.set("qt", "/" + solrDataImportPath); params.set("command", "full-import"); params.set("clean", "true"); params.set("commit", "true"); solr.query(params); } How can I insert just one single document into the index without having to index the whole thing? Are you

I have been using sharding with multiple basic solr server for clustering. I also used one embedded solr server (Solrj Java API) with many basic solr servers and connecting them by sharding as embedded solr server is the caller of them. I used the code line below for this purpose. SolrQuery query = new SolrQuery(); query.set("shards", "solr1URL,solr2URL,..."); Now, I have many embedded solr servers running on different computers and they are unaware of each others. I want to communicate them with each other by sharding. Is it possible? if yes how? if not what are the other options that you can

APDPlat 充分利用Compass的 OSEM 和 ORM integration 特性，提供了 简单易用 且 功能强大 的 内置搜索 特性。 APDPlat的内置搜索，在设计 简洁优雅 的同时，还具备了强大的 实时搜索 能力，用户只需用 注解 的方式在模型中指定需要搜索哪些字段（还可在模型之间进行关联搜索）就获得了搜索能力，而不用编写任何代码。平台自动处理索引维护、查询解析、结果高亮等支撑功能。 然而APDPlat的内置搜索只能在单机上面使用，不支持分布式，只能用于中小规模的场景。为了支持大规模的分布式搜索和实时分析，APDPlat 除了可以选择 Compass的进化版 ElasticSearch 外（ APDPlat拓展搜索之集成ElasticSearch ）， 还可以有另外一个选择 ，那就是 Solr 。 Solr提供了Java Client API（ SolrJ )，我们可以使用SolrJ来和Solr服务器进行交互。首先我们在pom.xml中引入SolrJ依赖： <dependency> <groupId>org.apache.solr</groupId> <artifactId>solr-solrj</artifactId> <version>${solrj.version}</version> </dependency> 接下来我们看一个APDPlat和

I've gone through the related questions on this site but haven't found a relevant solution. When querying my Solr4 index using an HTTP request of the form &facet=true&facet.field=country The response contains all the different countries along with counts per country. How can I get this information using SolrJ? I have tried the following but it only returns total counts across all countries, not per country: solrQuery.setFacet(true); solrQuery.addFacetField("country"); The following does seem to work, but I do not want to have to explicitly set all the groupings beforehand: solrQuery

首先，我是用的是solr5.5.4，但是我的solrj使用的4.10.3，这样在使用SolrCloud时，就会出现 org.apache.solr.common.SolrException: Collection not found: my_solr2 这样的异常，collection确定是存在，这时候，我们需要把solrj的版本修改为5.5.4，来保持一致。 这时候我单独测试没有问题了，奇怪的是，使用maven打包时，打进war包的还是4.10.3版本的solrj，在maven工程的pom文件的根目录文件夹，使用 mvn dependency:tree 命令可以查看jar包版本。 在仔细检查各个依赖工程时并没能发现有什么solrj版本不一致，将所有parent工程下面的子工程全部update，解决问题。 来源： CSDN 作者： 西皮皮 链接： https://blog.csdn.net/z56zzzz/article/details/77530889

I'm using Solr 4.10. I have enabled the /export request handler for an index by adding this to the solrconfig.xml (as mentioned here: https://cwiki.apache.org/confluence/display/solr/Exporting+Result+Sets ): <requestHandler name="/export" class="solr.SearchHandler"> <lst name="invariants"> <str name="rq">{!xport}</str> <str name="wt">xsort</str> <str name="distrib">false</str> </lst> <arr name="components"> <str>query</str> </arr> </requestHandler> Now I can use: http://localhost:8983/solr/index/select ?.... as well as http://localhost:8983/solr/index/export ?.... from a browser or curl. But,

I have a Bean Class Activity which associates List of Profiles and a User Bean. Now If I am trying to insert this Activity bean in Solr by SOLRJ, it is giving me null pointer exception. The Exception is causing by below piece of code: public <T> boolean insert (T bean) { try { UpdateResponse response = solrClient.addBean(bean); System.out.println("insert bean ElapsedTime: " + response.getElapsedTime()); solrClient.commit(); return true; } catch (IOException | SolrServerException e) { e.printStackTrace(); } return false; } Sanjay Madnani Refer below URL for nested document insertion and
