一、SolrJ基础 1、相关资料 API:http://lucene./solr/4_9_0/solr-solrj/ apache_solr_ref_guide_4.9.pdf:Client APIs---Using SolrJ http://wiki./solr/Solrj

二、SolrJ用于索引
三、SolrJ用于搜索 - package org.jediael.ui;
-
- import org.apache.solr.client.solrj.SolrQuery;
- import org.apache.solr.client.solrj.SolrServer;
- import org.apache.solr.client.solrj.impl.HttpSolrServer;
- import org.apache.solr.client.solrj.response.QueryResponse;
- import org.apache.solr.common.SolrDocument;
- import org.apache.solr.common.SolrDocumentList;
- import org.jediael.util.Constants;
-
- public class ReturnResult {
-
- public static void main(String[] args) throws Exception {
-
- String serverUrl = (args != null && args.length > 0) ? args[0]
- : "http://" + Constants.IP + ":" + Constants.PORT
- + "/solr/collection1";
- SolrServer solrServer = new HttpSolrServer(serverUrl);
-
-
- String queryString = (args != null && args.length > 1) ? args[1]
- : "*:*";
- SolrQuery solrQuery = new SolrQuery(queryString);
-
-
- solrQuery.set("qt", "/search");
-
- QueryResponse resp = solrServer.query(solrQuery);
-
- SolrDocumentList hits = resp.getResults();
-
- for (SolrDocument doc : hits) {
- for (String fieldName : doc.getFieldNames()) {
- System.out.println(fieldName + " : " + doc.getFieldValue(fieldName) + " ");
- }
- System.out.println("------------------------Next Document--------------------------------");
- }
-
- }
- }
1、使用SolrJ进行搜索,基本步骤如下: (1)创建一个SolrServer。 (2)创建一个SolrQuery,并使用set(String,String)进行参数的配置。 (3)调用SolrServer.query(solrQuery),返回QueryResponse。 (4)对QueryResponse进行分析处理。 2、以下语句用于指定使用哪个request handler进行搜索,若无指定,则使用默认的handler.默认是/select。若solrConfig.xml中无/select这个searchHandler,则返回以下错误 - <span style="font-family: Arial, Helvetica, sans-serif;">solrQuery.set("qt", "/search");</span>
HTTP Status 404 - /solr/collection1/select
type Status report message /solr/collection1/select description The requested resource is not available.
