Elastic AI agent builder 介绍（三）

news 2025/11/3 6:34:12

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：

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：

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：

我们再次重新查询：
