Gemini 2.0 模型拥有每日免费 500 次搜索请求配额。

在 #5431 按钮功能实现前，只能是不太灵活的环境变量来禁用该功能。（避免收费）

GEMINI_SEARCH_ENABLED 设为 1 则启用搜索功能，由于该功能可能收费，默认禁用。

参考文档，模型可以自动在合适的时机启用搜索，避免浪费配额，应当可以将 Grounding 搜索设为默认启用。

Starting with Gemini 2.0, Google Search is available as a tool. This means that the model can decide when to use Google Search.
从 Gemini 2.0 开始，Google 搜索作为工具提供。这意味着模型可以决定何时使用 Google 搜索。

注意启用的是只有 Gemini 2.0 模型才可享受的 googleSearch，1.5 系列与之无关。

根据测试，Grounding 暂时无法和 functionCall 共存，启用 functionCall 时会自动关闭 Grounding 搜索。

非常好的PR，我有如下疑问：如果我使用oneapi转发并重命名了我的Gemini模型，该环境变量是否仍然有效？

Very good PR, I have the following question: If I forward and rename my Gemini model using oneapi, is this environment variable still valid?

这样就不起作用了，只能是直接在 lobechat 配置 gemini 时有用。

This won't work, it can only be useful directly when configuring gemini in lobechat.

@arvinxx 老哥有空可以合一下这个，还是挺有用的。

@arvinxx Brother can combine this when he has time, it is quite useful.

@sxjeru 这个功能我有点不太想做成变量，目前针对搜索的需求非常普遍，我是计划做成一个应用级的能力的。包含两部分：

1. 应用级的搜索；
2. 模型级的搜索能力。
