elasticsearch多字段完成建议

Question

我想从多个领域得到建议。我找不到这样的例子，所以也许这不是最好的主意，但我对你的意见很感兴趣。

POST /authors
    {
       "mappings": {
          "author": {
             "properties": {
                "name": {
                   "type": "multi_field",
                   "fields": {
                      "name": {
                         "type": "string",
                         "index": "analyzed"
                      },
                      "ac": {
                         "type": "completion",
                         "index_analyzer": "simple",
                         "search_analyzer": "simple",
                         "payloads": true
                      }
                   }
                }
             }
          }
       }
    }

POST /authors/author/1
    {
       "name": "Fyodor Dostoevsky"
    }

POST /authors/_suggest

    {
       "authorsAutocomplete": {
          "text": "fyodor",
          "completion": {
             "field": "name.ac"
          }
       }
    }

要求是：

• GET查询适用于文本“fyodor”和“dostoevsky”，此示例仅适用于“fyodor”
• 启用筛选建议

我有什么想法可以实现这些？

Answer 1

首先，暗示者在多个领域都不能很好地工作，所以你可以把它放在外面。其次，为了使查询同时使用name和firstname，在索引数据时必须选择输出/输入。

Sense的工作代码示例：

POST authors

PUT authors/_mapping/author
{
    "properties" : {
        "name" : { "type" : "string" },
        "suggest" : { "type" : "completion"}
    }
}

POST authors/author/1
{
    "name": "Fyodor Dostoevsky",
    "suggest": {
        "input": ["Dostoevsky", "Fyodor"],
        "output": "Fyodor Dostoevsky"
    }
}

POST authors/_suggest
{
    "authorsAutocomplete": {
        "text": "d",
        "completion": {
            "field": "suggest"
        }
    }
}

DELETE authors

结果：

{
    "_shards": {
        "total": 5,
        "successful": 5,
        "failed": 0
    },
    "authorsAutocomplete": [
        {
            "text": "d",
            "offset": 0,
            "length": 1,
            "options": [
                {
                    "text": "Fyodor Dostoevsky",
                    "score": 1
                }
            ]
        }
    ]
}

筛选器不可用于建议。要实现某种筛选，您可以查看这篇关于在建议中使用上下文的博客文章。
