    配置 3节点的集群，同时满足以下要求->不允许删除数据的情况下，保证集群状态为 Green ,这句话能解释下吗？具体是怎么做的？请教下哈

    作者回复: 也就是说，会给你一个集群，health的状态是红色。你需要通过查看各种API，找到分片不能分配的原因。因为，如果你通过删除索引，确实可以让集群变绿，但是会导致数据丢失，所以，考试的会要求你不能删除任何数据

    启动第二个节点时遇到了新问题：都是在一台机器上http的port不能绑在同一个端口号上。

    好解决，只对coordinator节点进行http访问，把模拟题改一改，再起一个单独的coordinator节点，然后只有这个节点指定http.port，也便于之后的Kibana访问。

    对ES的感觉是逐渐好了起来啊！趟了那么多的开源产品，ES做得确实棒，值得进一步的智力投资。

    哈哈，被我猜到了，
    把前缀补全就OK了。
    ssl.keystore.password -> xpack.security.transport.ssl.keystore.password
    ssl.truststore.password -> xpack.security.transport.ssl.truststore.password
    然后添加上针对http的keystore password
    xpack.security.http.ssl.keystore.password=changeme
    xpack.security.http.ssl.truststore.password=changeme

    完整的命令行：
    ./bin/elasticsearch -Ecluster.name=geektime -Enode.name=node1 -Epath.data=node1_data -Epath.logs=node1_log -Enode.master=true -Enode.data=false -Enode.ingest=false -Enode.ml=false -Expack.security.enabled=true -Expack.security.transport.ssl.enabled=true -Expack.security.transport.ssl.verification_mode=certificate -Expack.security.transport.ssl.keystore.path=certs/elastic-certificates.p12 -Expack.security.transport.ssl.truststore.path=certs/elastic-certificates.p12 -Expack.security.http.ssl.enabled=true -Expack.security.http.ssl.keystore.path=certs/elastic-certificates.p12 -Expack.security.http.ssl.truststore.path=certs/elastic-certificates.p12 -Ehttp.port=9200 -Expack.security.transport.ssl.keystore.password=changeme -Expack.security.transport.ssl.truststore.password=changeme -Expack.security.http.ssl.keystore.password=changeme -Expack.security.http.ssl.truststore.password=changeme

    在启动ES的命令行中如何带上keystore的密码，生成基于ca的授权证书时输入了密码，启动时报failed to decrypt safe contents entry，感觉是启动时访问证书需要密码，但是如何在命令行中指定密码呢？实在不行只有搞成那种不带密码的证书了。

    执行的命令行：
    ./bin/elasticsearch -Ecluster.name=geektime -Enode.name=node1 -Epath.data=node1_data -Epath.logs=node1_log -Enode.master=true -Enode.data=false -Enode.ingest=false -Enode.ml=false -Expack.security.enabled=true -Expack.security.transport.ssl.enabled=true -Expack.security.transport.ssl.verification_mode=certificate -Expack.security.transport.ssl.keystore.path=certs/elastic-certificates.p12 -Expack.security.transport.ssl.truststore.path=certs/elastic-certificates.p12 -Expack.security.http.ssl.enabled=true -Expack.security.http.ssl.keystore.path=certs/elastic-certificates.p12 -Expack.security.http.ssl.truststore.path=certs/elastic-certificates.p12 -Ehttp.port=9200 -Essl.keystore.password=changeme -Essl.truststore.password=changeme

    指定了 ssl.keystore.password 和 ssl.truststore.password 也不行，不太确定是这两个参数是否是有效解决这个问题所需的参数。

    错误信息：

    老师，可以加一个模拟测试的参考 答案吗，自己做了可能想看看跟你的有什么区别。

    作者回复: 有很多测试都是基于一些实际操作的。很难给出参考答案，我在课程的readme中放了几个官方放出的攻略视频，你可以看一下

    In an index mapping, one field uses analyzer "english"; When search, is it true that using the default analyzer same as field mapping?

    https://www.elastic.co/guide/en/elasticsearch/reference/7.1/search-analyzer.html
    By default, queries will use the analyzer defined in the field mapping, but this can be overridden with the search_analyzer setting.
