+# MiniSearch
+
+A minimalist web-searching app with an AI assistant that runs directly from your browser.
+
+Live demo: https://felladrin-minisearch.hf.space
+
+## Screenshot
+
+![MiniSearch Screenshot](https://github.com/user-attachments/assets/f8d72a8e-a725-42e9-9358-e6ebade2acb2)
+
+## Features
+
+- **Privacy-focused**: [No tracking, no ads, no data collection](https://docs.searxng.org/own-instance.html#how-does-searxng-protect-privacy)
+- **Easy to use**: Minimalist yet intuitive interface for all users
+- **Cross-platform**: Models run inside the browser, both on desktop and mobile
+- **Integrated**: Search from the browser address bar by setting it as the default search engine
+- **Efficient**: Models are loaded and cached only when needed
+- **Customizable**: Tweakable settings for search results and text generation
+- **Open-source**: [The code is available for inspection and contribution at GitHub](https://github.com/felladrin/MiniSearch)
+
+## Prerequisites
+
+- [Docker](https://docs.docker.com/get-docker/)
+
+## Getting started
+
+Here are the easiest ways to get started with MiniSearch. Pick the one that suits you best.
+
+**Option 1** - Use [MiniSearch's Docker Image](https://github.com/felladrin/MiniSearch/pkgs/container/minisearch) by running in your terminal:
+
+```bash
+docker run -p 7860:7860 ghcr.io/felladrin/minisearch:main
+```
+
+**Option 2** - Add MiniSearch's Docker Image to your existing Docker Compose file:
+
+```yaml
+services:
+  minisearch:
+    image: ghcr.io/felladrin/minisearch:main
+    ports:
+      - "7860:7860"
+```
+
+**Option 3** - Build from source by [downloading the repository files](https://github.com/felladrin/MiniSearch/archive/refs/heads/main.zip) and running:
+
+```bash
+docker compose -f docker-compose.production.yml up --build
+```
+
+Once the container is running, open http://localhost:7860 in your browser and start searching!
+
+## Frequently asked questions
+
+<details>
+  <summary>How do I search via the browser's address bar?</summary>
+  <p>
+    You can set MiniSearch as your browser's address-bar search engine using the pattern <code>http://localhost:7860/?q=%s</code>, in which your search term replaces <code>%s</code>.
+  </p>
+</details>
+
+<details>
+  <summary>Can I use custom models via OpenAI-Compatible API?</summary>
+  <p>
+    Yes! For this, open the Menu and change the "AI Processing Location" to <code>Remote server (API)</code>. Then configure the Base URL, and optionally set an API Key and a Model to use.
+  </p>
+</details>
+
+<details>
+  <summary>How do I restrict the access to my MiniSearch instance via password?</summary>
+  <p>
+    Create a <code>.env</code> file and set a value for <code>ACCESS_KEYS</code>. Then reset the MiniSearch docker container.
+  </p>
+  <p>
+    For example, if you to set the password to <code>PepperoniPizza</code>, then this is what you should add to your <code>.env</code>:<br/>
+    <code>ACCESS_KEYS="PepperoniPizza"</code>
+  </p>
+  <p>
+    You can find more examples in the <code>.env.example</code> file.
+  </p>
+</details>
+
+<details>
+  <summary>I want to serve MiniSearch to other users, allowing them to use my own OpenAI-Compatible API key, but without revealing it to them. Is it possible?</summary>
+  <p>Yes! In MiniSearch, we call this text-generation feature "Internal OpenAI-Compatible API". To use this it:</p>
+  <ol>
+    <li>Set up your OpenAI-Compatible API endpoint by configuring the following environment variables in your <code>.env</code> file:
+      <ul>
+        <li><code>INTERNAL_OPENAI_COMPATIBLE_API_BASE_URL</code>: The base URL for your API</li>
+        <li><code>INTERNAL_OPENAI_COMPATIBLE_API_KEY</code>: Your API access key</li>
+        <li><code>INTERNAL_OPENAI_COMPATIBLE_API_MODEL</code>: The model to use</li>
+        <li><code>INTERNAL_OPENAI_COMPATIBLE_API_NAME</code>: The name to display in the UI</li>
+      </ul>
+    </li>
+    <li>Restart MiniSearch server.</li>
+    <li>In the MiniSearch menu, select the new option (named as per your <code>INTERNAL_OPENAI_COMPATIBLE_API_NAME</code> setting) from the "AI Processing Location" dropdown.</li>
+  </ol>
+</details>
+
+<details>
+  <summary>How can I contribute to the development of this tool?</summary>
+  <p>Fork this repository and clone it. Then, start the development server by running the following command:</p>
+  <p><code>docker compose up</code></p>
+  <p>Make your changes, push them to your fork, and open a pull request! All contributions are welcome!</p>
+</details>
+
+<details>
+  <summary>Why is MiniSearch built upon SearXNG's Docker Image and using a single image instead of composing it from multiple services?</summary>
+  <p>There are a few reasons for this:</p>
+  <ul>
+    <li>MiniSearch utilizes SearXNG as its meta-search engine.</li>
+    <li>Manual installation of SearXNG is not trivial, so we use the docker image they provide, which has everything set up.</li>
+    <li>SearXNG only provides a Docker Image based on Alpine Linux.</li>
+    <li>The user of the image needs to be customized in a specific way to run on HuggingFace Spaces, where MiniSearch's demo runs.</li>
+    <li>HuggingFace only accepts a single docker image. It doesn't run docker compose or multiple images, unfortunately.</li>
+  </ul>
