elasticsearch Elasticsearch匹配查询不匹配带撇号的文档

我正在为localities autocomplete构建一个搜索程序，它是Google Maps one的一个简单版本。我使用的查询似乎一切正常：

{
  "query": {
    "bool": {
      "must": {
        "multi_match": {
          "query": "Ametlla",
          "type": "best_fields",
          "fields": [
            "locality",
            "alternative_names"
          ],
          "operator": "and"
        }
      },
      "filter": {
        "term": {
          "country_code": "ES"
        }
      }
    }
  }
}

我发现的问题与西班牙的一座城市有关：Lametlla de Mar

/localities\u索引/localities/10088

{
  "_index": "localities_index",
  "_type": "localities",
  "_id": "10088",
  "_version": 1,
  "_seq_no": 133,
  "_primary_term": 4,
  "found": true,
  "_source": {
    "country_code": "es",
    "locality": "L'Ametlla de Mar",
    "alternative_names": []
  }
}

您可以搜索

Ametlla

，并将其匹配（请参见下面的部分名称示例查询）

            ]
          }
        ]
      }
    ]
  }
}

但如果你使用它的全名，它就不是

我曾尝试将

标点符号
添加到token\u chars中，正如我在上所看到的，但没有成功。因此，我尝试将
'
添加为
自定义令牌\u字符
，但也没有效果。

您可以在自定义分析器中使用，并在字段（包含它们的位置）上使用，还可以使用您已经在使用的
匹配
查询，因为它将使用索引时使用的同一分析器，您将获得预期的结果。
如果我删除文档并再次添加它，它将与该筛选器一起工作。但是，如果我关闭索引，更新设置并添加标记过滤器，然后重新打开索引，则该操作不起作用。@blacksoul您需要重新为文档编制索引，然后只有它将更新的标记存储在反向索引中并起作用。很高兴它对您有效，只需重新编制所有文档的索引，您就可以开始了，也别忘了向上投票并接受答案：）
