- Implemented a search button in the header of each documentation page. - Added a search modal that allows users to input search queries. - Integrated a JavaScript search feature that fetches and displays results from a new `pages-data.json` file. - Each documentation page now includes a search overlay for improved navigation. - Updated the main JavaScript file to handle search logic, including result highlighting and navigation. - Created a `pages-data.json` file containing metadata for all documentation pages to facilitate search functionality.

<h1>What's Next</h1>
|
||
<p>Tourお疲れさまでした！ cpp-httplibの基本はひと通り押さえましたね。でも、まだまだ便利な機能があります。Tourで取り上げなかった機能をカテゴリー別に紹介します。</p>
|
||
<h2>Streaming API</h2>
|
||
<p>LLMのストリーミング応答や大きなファイルのダウンロードでは、レスポンス全体をメモリに載せたくないですよね。<code>stream::Get()</code> を使えば、データをチャンクごとに処理できます。</p>
