title: LLM 驱动搜索引擎在 2023 年都做了些什么 date: 2023-12-27 tags: – LLM – 大模型 categories: – 洞见

有人说，大语言模型（Large Language Model，LLM）是下一代搜索引擎。这个说法有一定道理，但不完全对。

不完全对的地方在于，搜索引擎继续保留着索引和检索的基础设施，而只在检索结果排序和呈现阶段引入 LLM 的能力。LLM 带来的改变是搜索引擎将内容聚合和生成的门槛降到非常低，再加上对话形式的用户交互界面，这些叠加在一起让搜索引擎更接近问答系统。相比之下，LLM 本身其实并没有能力进行长期的知识存储和检索。

有道理的地方在于，搜索引擎一直在试图解决 LLM 大热之前就存在的用户问题，而 LLM 的引入让搜索引擎距离那个长期愿景更近了一步。这里有两个方面：一是用户对自然语言交互的需求，二是用户对问题直接解答的需求。

用户需求中蕴含的长期愿景就是搜索引擎朝着问答系统演进。LLM 只是让这个过程加速了。

2023 年里，主流的通用搜索引擎都发布了 LLM 驱动的新产品。Google 于 2023 年初推出的 Bard 产品就是在 Google 搜索基础上构建的对话式搜索服务。Bing 则通过与 OpenAI 的合作，在 GPT-4 的基础上推出了新版 Bing 搜索。百度等中文搜索引擎提供商也纷纷推出类似功能。这篇文章主要关注 Google 和 Bing 这两家主要厂商的产品进展。

Google

Google 官方博客上记录了 LLM 驱动的搜索引擎功能在 2023 年的以下进展：

• Bard becomes more visual
  • 能够结合图像进行对话
  • 能够生成、编辑和导出图像
• Search Generative Experience
  • 搜索结果页面上方出现由 LLM 生成的总结内容
  • 生成摘要等内容同时保留网页链接
• Help me write
  • 在 Chrome 浏览器中实现的文本生成功能
• AI-powered overview
  • 基于搜索历史生成个性化总结
  • 支持细化搜索需求，建议后续搜索内容
• Perspective summaries
  • 对搜索内容提供不同视角的总结摘要

上述功能都是围绕着内容聚合和自然语言理解来增强搜索结果的。这些功能大都依赖 LLM 的能力，但 LLM 其实不是必选项。比如说，Google 之前就尝试过利用页面抽取的方式直接在搜索结果页回答问题。但 LLM 的引入让这个过程更加自然和通用。

Google 搜索引擎在 2023 年的改进表现出一种保守策略。Google 本质上在做以下两件事：利用 LLM 提高搜索结果的质量，并增强与搜索相关的功能（如浏览器中的文本生成）。他们似乎没有像微软那样激进地改变搜索体验。

Principles of Jet Aeration

Jet aeration is a powerful method for adding oxygen to water. It uses high-speed water jets to mix air into liquid. This process is key for many water treatment and aquaculture systems.

Mechanics of Jet Aeration

Jet aeration works by forcing water through small nozzles at high speed. This creates a spray of tiny droplets. As the droplets move through the air, they absorb oxygen.

When the water falls back into the tank, it brings the oxygen with it. The turbulence from the jets also helps mix the oxygenated water throughout the tank.

Hydro jet aeration systems often use pumps to recirculate water. This keeps the process going without wasting water.
