elk使用爬坑记录 4 之 Elasticsearch中ik分词器的使用

悠悠 2024-04-18 14:13 79阅读 0赞

ik分词器对中文支持较好的开源分词器，开源地址为[https://github.com/medcl/elasticsearch-analysis-ik][https_github.com_medcl_elasticsearch-analysis-ik]

使用注意事项：

1.  ik分词器的版本必须和elasticsearch的版本对应;
2.  官网上7.x的源码下来后，编译出来的版本仍然是7.0的，需要手动在下载的源码中elasticsearch的版本改正为对应的7.X版本，应该是开发者手误;

将 <elasticsearch.version>7.0.0</elasticsearch.version>更正如下：

<properties>
            <elasticsearch.version>7.3.1</elasticsearch.version>
            <maven.compiler.target>1.8</maven.compiler.target>
            <elasticsearch.assembly.descriptor>${project.basedir}/src/main/assemblies/plugin.xml</elasticsearch.assembly.descriptor>
            <elasticsearch.plugin.name>analysis-ik</elasticsearch.plugin.name>
            <elasticsearch.plugin.classname>org.elasticsearch.plugin.analysis.ik.AnalysisIkPlugin</elasticsearch.plugin.classname>
            <elasticsearch.plugin.jvm>true</elasticsearch.plugin.jvm>
            <tests.rest.load_packaged>false</tests.rest.load_packaged>
            <skip.unit.tests>true</skip.unit.tests>
            <gpg.keyname>4E899B30</gpg.keyname>
            <gpg.useagent>true</gpg.useagent>
        </properties>
