PHP使用elasticSearch进行分词
安装最行版本ElasticSearch，推荐使用rpm -ivh安装，下载地址：https://github.com/elastic/elasticsearch/releases
安装方式两种：在线安装、离线安装
（1）在线安装：
cd /usr/share/elasticsearch/ ./bin/elastic-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.2.4/elasticsearch-analysis-ik-6.2.4.zip
离线安装：需要用到maven，
下载ik源码到磁盘，进入目录，
mvn package，
然后会下载依赖包，生成一个target文件夹，
进入target/releases文件夹，把打包好的文件移动到plugins文件夹，并unzip解压，
重启elasticsearch服务，
systemctrl status elasticsearch.service
确认下服务是否成功启动，如有故障进行 排查（点击看看常见错误），
4.PHP安装composer
5.composer安装
composer reuqire "elasticsearch/elasticsearch" 6.PHP代码调用： $client=ClientBuilder::create()->setHosts(['192.168.32.128'])->build(); $params['index'] = 'index'; $params['body'] = [ // 'analyzer' => 'ik_max_word', 'analyzer' => 'ik_smart', // 'text' => '英雄联盟最强王者' // 'text' => '中华人民共和国国歌' 'text' => 'based index manager for Elasticsearch' ]; $res=$client ->indices()->analyze($params);
打印结果如下：
array(1) {
["tokens"] => array(4) {
[0] => array(5) {
["token"] => string(5) "based"
["start_offset"] => int(0)
["end_offset"] => int(5)
["type"] => string(7) "ENGLISH"
["position"] => int(0)
}
[1] => array(5) {
["token"] => string(5) "index"
["start_offset"] => int(6)
["end_offset"] => int(11)
["type"] => string(7) "ENGLISH"
["position"] => int(1)
}
[2] => array(5) {
["token"] => string(7) "manager"
["start_offset"] => int(12)
["end_offset"] => int(19)
["type"] => string(7) "ENGLISH"
["position"] => int(2)
}
[3] => array(5) {
["token"] => string(13) "elasticsearch"
["start_offset"] => int(24)
["end_offset"] => int(37)
["type"] => string(7) "ENGLISH"
["position"] => int(3)
}
}
}
