Solr API操作
1、需要在/usr/local/services/solr/solr-4.10.3/example/solr/collection1/conf的solrconfig.xml加上 <requestHandler name="/select" class="solr.SearchHandler"> <!-- default values for query parameters can be specified, these will be overridden by parameters in the request --> <lst name="defaults"> <str name="echoParams">explicit</str> <int name="rows">10</int> <str name="df">text</str> </lst> <!-- 这行代码非常重要，如果没有这行，拼写检查，是不起作用的--> <arr name="last-components"> <str>spellcheck</str> 以便spell能够生效 2、在/usr/local/services/solr/solr-4.10.3/example/solr/collection1/conf的schema.xml修改，加上字段，否则会报错 如： <field name="id"
Solr Range Facets dynamically modifying the ranges based on the search query
问题 So here is what I am trying to do. I have a facet defined on the price field. 1) When there is a query for "wordA" I want the facets to be from 0-1000 divided in 5 intervals since my maximum price for "wordA" will never exceed 1000 2) When there is a query for "wordB" I want the facets to be from 0-50 divided in 5 intervals since my maximum price for the query "wordB" will never exceed 50. So basically I want the facet range to change dynamically so that I don't end up with a range of 0-1000

Is there a SolrJ query builder?
问题 Using solr 5.2.0 was wondering is there a query builder API/Jar/Ckient similar to Elasticsearch query builder API or do we have to bassically do String Kungfu to build queries in Solr? 回答1: Unfortunately, in SolrJ there is no such thing as a Builder for the query that goes into the q -Parameter. BUT: As Solr already operates on Lucene, we can as well use the Lucene QueryBuilder. The resulting Query objects (e.g. PhraseQuery) have a toString() method that provides you with the query string you
Solr第二讲——SolrJ客户端的使用与案例
一、Solrj的使用 1.什么是Solrj solrj是访问Solr服务的java客户端（就像通过jedis操作redis一样），提供索引和搜索的请求方法，SolrJ通常在嵌入在业务系统中，通过SolrJ的API接口操作Solr服务，如下图： 2.如何使用 需要的是solrj的包与拓展服务包 使用solrj完成索引的维护： 在solr中，索引库中都会存在一个唯一键，如果一个Document的 id 存在，则执行修改操作，如果不存在，则执行添加操作。 添加/修改索引： 1、 创建 HttpSolrServer 对象，通过它和 Solr 服务器建立连接。 2、 创建 SolrInputDocument 对象，然后通过它来添加域。 3、 通过 HttpSolrServer 对象将 SolrInputDocument 添加到索引库。 4、 提交。 @Test public void addDocument() throws Exception { // 1、 创建HttpSolrServer对象，通过它和Solr服务器建立连接。 // 参数：solr服务器的访问地址 HttpSolrServer server = new HttpSolrServer("http:/
