Elastic AI agent builder 介绍（三）

在这篇文章里，我将使用 gpt-oss 大模型来展示如何在 AI agent builder 中进行使用。有关 gpt-oss 的安装请参考文章 "如何使用 Ollama 在本地设置和运行 GPT-OSS"。我们需要按照这篇文章来安装我们的 gpt-oss。

细心的开发者，可能在之前的版本中运行如下的查询：

我们研究了一下原因。这个其实就我们在写入文档时，我们的 mapping 是这样定义的：

复制代码

PUT /people
{
  "mappings": {
    "properties": {
      "id": {
        "type": "integer"
      },
      "name": {
        "type": "text"
      },
      "description": {
        "type": "text",
        "copy_to": "des_semantic"
      },
      "des_semantic": {
        "type": "semantic_text"
      },
      "sex": {
        "type": "keyword"
      },
      "age": {
        "type": "integer"
      },
      "address": {
        "type": "text"
      },
      "location": {
        "type": "geo_point"
      }
    }
  }
}

很显然，des_semantic 在没有定义端点的情况下，默认的就是使用系数向量模型 ELSER。我们可以参考文章 "Elasticsearch：使用推理端点及语义搜索演示"。在目前的阶段，由于 ELSER 模型不支持中文，这也导致我们的查询得不到想要的结果。我们可以采用多语言模型。

我们使用如下的 API 来获得所有的 endpoints：

我们可以看到已经为我们定制好的 .multilingual-e5-small-elasticsearch id。我们可以重新定义我们的索引 mapping：

复制代码

DELETE people

PUT /people
{
  "mappings": {
    "properties": {
      "id": {
        "type": "integer"
      },
      "name": {
        "type": "text"
      },
      "description": {
        "type": "text",
        "copy_to": "des_semantic"
      },
      "des_semantic": {
        "type": "semantic_text",
        "inference_id": ".multilingual-e5-small-elasticsearch"
      },
      "sex": {
        "type": "keyword"
      },
      "age": {
        "type": "integer"
      },
      "address": {
        "type": "text"
      },
      "location": {
        "type": "geo_point"
      }
    }
  }
}

然后，我们再次写入文档：

复制代码

我们再次重新查询：

很显然，这次我们得到我们想要的答案了。

最近我们 Elastic 公司收购了 JINA。JINA 支持多模态的嵌入模型，它同时也支持多语言模型。我们可以参考文章 "使用 Jina Embeddings v2 在 Elasticsearch 中进行后期分块" 来进行测试。
