Question

term suggester documentation 列出了术语建议器的基础知识，但这让我想知道如何从多个领域找到建议并将它们组合起来。我可能可以在事后想出一些实现，但我想知道是否缺少某些设置。

例如，假设我想从三个不同的领域获得建议

GET product-search-product/_search
{
  "suggest": {
    "text": "som typu here",
    "my-suggest-1": {
      "term": {
        "size": 1,
        "max_edits": 1,
        "prefix_length": 3,
        "field": "field_one"
      }
    },
    "my-suggest-2": {
      "term": {
        "size": 1,
        "max_edits": 1,
        "prefix_length": 3,
        "field": "field_two"
      }
    },
    "my-suggest-3": {
      "term": {
        "size": 1,
        "max_edits": 1,
        "prefix_length": 3,
        "field": "field_three"
      }
    }
  }
}

我可以使用这个 returns 结果，但我必须弄清楚哪个字段有 "best" 建议。

"suggest": {
"my-suggest-1": [
  {
    "text": "som",
    ...
    "options": [
      {
        "text": "somi"
        ...
      }
    ]
  },
  {
    "text": "typu",
    ...
    "options": [
      {
        "text": "typo"
        ...
      }
    ]
  },
  {
    "text": "here",
    ...
    "options": []
  }
],
"my-suggest-2": [
  {
    "text": "som",
    ...
    "options": [
      {
        "text": "some"
        ...
      }
    ]
  },
  {
    "text": "typu",
    ...
    "options": []
  },
  {
    "text": "here",
    ...
    "options": []
  }
],
"my-suggest-3": [
  {
    "text": "som",
    ...
    "options": []
  },
  {
    "text": "typu",
    ...
    "options": [
      {
        "text": "typa"
        ...
      }
    ]
  },
  {
    "text": "here",
    ...
    "options": []
  }
]

}

在我看来，好像我必须实施一些东西来确定哪个领域提出了最好的建议。有没有办法在建议者中将这些结合起来以便它可以为我做到这一点？

Phrase suggester 适合我的情况，并且存在短语 suggester candidate generators 似乎可以解决我的问题。
