无法在ElasticSearch中将映射更改为non_analyzed

Question

我有一个doctype，其中包含以下映射：

import {Component, OnInit, ViewEncapsulation, Input} from '@angular/core';

import './baBootStrapTags.loader.ts';

@Component({
  selector: 'ba-tags-input',
  template: require('./baBootStrapTags.html'),
  encapsulation: ViewEncapsulation.None,
})
export class BaBootStrapTags implements OnInit {
  cities: Bloodhound; // <----- ERROR HERE
  @Input() config:Object = {
    itemValue: 'value',
    itemText: 'text',
    typeaheadjs: {
      name: 'cities',
      displayKey: 'text',
      source: this.cities.ttAdapter()
    }
  };
}

我正在尝试将某些字段从GET my_index/my_doctype/_mapping { "my_index": { "mappings": { "my_doctype": { "properties": { "@timestamp": { "type": "date", "format": "strict_date_optional_time||epoch_millis" }, "@version": { "type": "string" }, "prod_id": { "type": "string" }, "host": { "type": "string" }, "message": { "type": "string" }, "path": { "type": "string" }, "img_path": { "type": "string" }, "tags": { "type": "string" } } } } } } 更改为analyzed，因此我会运行此请求：

non_analyzed

但是我收到以下错误：

PUT my_index/_mapping/my_doctype 
{
  "properties": {
    "prod_id": {
      "type": "string",
      "index": "not_analyzed"
    },
    "img_path": {
      "type": "string",
      "index": "not_analyzed"
    }
  }
}

如何将字段“prod_id”和“img_path”更改为{ "error": { "root_cause": [ { "type": "illegal_argument_exception", "reason": "Mapper for [img_path] conflicts with existing mapping in other types:\n[mapper [img_path] has different [index] values, mapper [img_path] has different [doc_values] values, cannot change from disabled to enabled, mapper [img_path] has different [analyzer], mapper [img_path] is used by multiple types. Set update_all_types to true to update [omit_norms] across all types., mapper [img_path] is used by multiple types. Set update_all_types to true to update [search_analyzer] across all types., mapper [img_path] is used by multiple types. Set update_all_types to true to update [search_quote_analyzer] across all types.]" } ], "type": "illegal_argument_exception", "reason": "Mapper for [img_path] conflicts with existing mapping in other types:\n[mapper [img_path] has different [index] values, mapper [img_path] has different [doc_values] values, cannot change from disabled to enabled, mapper [img_path] has different [analyzer], mapper [img_path] is used by multiple types.

Answer 1

您无法更改现有字段的映射。你有两个解决方案：

1. 您可以删除索引，使用正确的映射重新创建索引并重新索引数据
2. 您可以创建not_analyzed子字段并重新索引数据

第二个解决方案是这样的：

PUT my_index/_mapping/my_doctype 
{
  "properties": {
    "prod_id": {
      "type": "string",
      "fields": {
        "raw": {
          "type": "string",
          "index": "not_analyzed"
        }
      }
    },
    "img_path": {
      "type": "string",
      "fields": {
        "raw": {
          "type": "string",
          "index": "not_analyzed"
        }
      }
    }
  }
}

然后，您可以在重新编制数据索引后使用prod_id.raw和img_path.raw。
