| 在继续之前，我们将绕道讨论一下在分布式环境中搜索是怎么执行的。 | ||
| ((("distributed search execution"))) 这比我们在 <<distributed-docs>> 章节讨论的基本的 _增-删-改-查_ (CRUD)请求要复杂一些。 |

| 搜索需要一种更加复杂的执行模型因为我们不知道查询会命中哪些文档: 这些文档有可能在集群的任何分片上。 | ||
| 一个搜索请求必须询问我们关注的索引（index or indices）的所有分片的某个副本来确定它们是否含有任何匹配的文档。 |

我们关注的索引（index or indices）--》我们关注的单个或多个索引 这样子会不会比较好点？可不改

仅仅完成事情的一半--》仅仅完成了搜索过程的一半 只是觉得有点别扭，可不改

| Read this chapter to gain a taste for how things work, and to know where the | ||
| information is in case you need to refer to it in the future, but don't be | ||
| overwhelmed by the detail. | ||
| 这章的阅读目的只为初步了解下工作原理，假使将来需要时可以及时找到这些知识， |
