本文详细介绍如何在Solr7.4中配置IK分词器，包括在managed-schema.xml中添加分词器配置，以及在catalina.bat中设置日志路径。此外，还提供了Solr7.4的API操作示例，数据导入的全量和增量命令，以及解决IndexLocked和ErrorOpeningNewSearcher问题的方法。

managed-schema.xml中增加ik分词器（或 5版本之前的是 schema.xml ）

<!-- 添加IK分词 -->
	 <fieldType name="text_ik" class="solr.TextField">   
			   <analyzer type="index" isMaxWordLength="false" class="org.wltea.analyzer.lucene.IKAnalyzer"/>   
			   <analyzer type="query" isMaxWordLength="true" class="org.wltea.analyzer.lucene.IKAnalyzer"/>   
	 </fieldType>

catalina.bat中配置日志：

set JAVA_OPTS="-Dsolr.log.dir=d:/solr-7.4.0/solr_home/logs"

Solr7.4.0应用部署Demo，比较全面完整:

Solr7.4.0的API（Solrj）操作

全量：

增量：

solr7.4定时任务增量或全量同步数据： https://developer.aliyun.com/article/660563

注意：deltaQuery="select T_ID from SW_MH_TRAVELNOTE where T_CREATETIME > ‘${dih.last_index_time}’ " 该T_CREATETIME 类型必须是时间戳timestamp,日期都不行 datetime,date
真是一个大坑。

<entity name="travelNoteData" pk="T_ID" transformer="DateFormatTransformer"
            query="SELECT T_ID,T_TITLE,T_CONTENT,5 as s_type FROM SW_MH_TRAVELNOTE where T_STATE = 1 ORDER BY T_CREATETIME DESC"
			deltaQuery="select T_ID from SW_MH_TRAVELNOTE where T_ID > 50 "  
			deletedPkQuery="select T_ID from SW_MH_TRAVELNOTE where T_STATE &lt;&gt; 1"
            deltaImportQuery="select T_ID,T_TITLE,T_CONTENT,5 as s_type from SW_MH_TRAVELNOTE where T_ID = '${dih.delta.T_ID}'" >
			
            <field column='T_ID' name='id' />
            <field column='T_TITLE' name='name' />
			<field column='T_CONTENT' name='content' />
			<field column='s_type' name='type' />
        </entity>

solr7.4版本的定时任务jar要放在tomcat的lib下面 solr-dataimportscheduler-1.1.0.jar

SolrException: Index locked 和 Error opening new searcher 最终解决方案（找了好久才解决）

二、解决方法
以上错误研究了很长时间，网上百度goole了很多解决方法，又是重启tomcat又是重新建立solr配置都无效，无意中用以下方法终于解决了。

只需要在solrconfig.xml中配置 true这个就可以。

1、首先，删除/data/index/write.lock文件，

2、然后，登录 Apache Tomcat 管理界面，点击进入Manager App ，在Applications列表中找到solr站点，点击Reload按钮

Solr7.4 如果修改过solr服务中的文件时，再次启动要删除掉write.lock文件
