我的ES自定义分析器没有用？

Question

我正在使用 Elasticsearch 并使用以下映射和设置信息创建索引。我遇到的问题是我的字段 geography.locality 应该使用 'name_analyser' 似乎没有使用它。

            }
          }
        }
      }
    }
  }
}

这是 ES 为该索引注册的映射给出的输出。

      },

  }
}

有人知道我做错了什么吗？我有点迷茫了。

Answer 1

我猜该索引存在并且您正在尝试使用新的分析器更新设置。这在实时索引上是不允许的。

提交更新后的设置有没有错误？

看看这个帖子 - Change settings and mappings on existing index in Elasticsearch

这里http://www.elastic.co/guide/en/elasticsearch/reference/1.x/indices-update-settings.html#update-settings-analysis

Answer 2

你打错了 :-)，实际上是两个：

    "locality": {
      "type": "string",
      "analyser": "name_analyser"
    },

在 address 和 geography 中。它应该是 analyzer 而不是 analyser（带有 s）。

另外，这里也一样：

    "analyser": {
      "name_analyser": {
        "tokenizer": "whitespace",
    ...

我的ES自定义分析器没有用？

My ES custom analyser is not used?
