 - **Frontend (`ui` directory)**: This is a Next.js application holding all user interface components. It's a self-contained environment that manages everything the user interacts with.
 - **Backend (root and `src` directory)**: The backend logic is situated in the `src` folder, but the root directory holds the main `package.json` for backend dependency management.

-## Overview
-
-Perplexica is an open-source AI-powered searching tool or an AI-powered search engine that goes deep into the internet to find answers. Inspired by Perplexity AI, it's an open-source option that not just searches the web but understands your questions. It uses advanced machine learning algorithms like similarity searching and embeddings to refine results and provides clear answers with sources cited.
-
-Using SearxNG to stay current and fully open source, Perplexica ensures you always get the most up-to-date information without compromising your privacy.
-
-Want to know more about its architecture and how it works? You can read it [here](https://github.com/ItzCrazyKns/Perplexica/tree/master/docs/architecture/README.md).

-## Features
-
-- **Local LLMs**: You can make use local LLMs such as Llama3 and Mixtral using Ollama.
-- **Two Main Modes:**
-  - **Copilot Mode:** (In development) Boosts search by generating different queries to find more relevant internet sources. Like normal search instead of just using the context by SearxNG, it visits the top matches and tries to find relevant sources to the user's query directly from the page.
-  - **Normal Mode:** Processes your query and performs a web search.
-- **Focus Modes:** Special modes to better answer specific types of questions. Perplexica currently has 6 focus modes:
-  - **All Mode:** Searches the entire web to find the best results.
-  - **Writing Assistant Mode:** Helpful for writing tasks that does not require searching the web.
-  - **Academic Search Mode:** Finds articles and papers, ideal for academic research.
-  - **YouTube Search Mode:** Finds YouTube videos based on the search query.
-  - **Wolfram Alpha Search Mode:** Answers queries that need calculations or data analysis using Wolfram Alpha.
-  - **Reddit Search Mode:** Searches Reddit for discussions and opinions related to the query.
-- **Current Information:** Some search tools might give you outdated info because they use data from crawling bots and convert them into embeddings and store them in a index. Unlike them, Perplexica uses SearxNG, a metasearch engine to get the results and rerank and get the most relevant source out of it, ensuring you always get the latest information without the overhead of daily data updates.
-
-It has many more features like image and video search. Some of the planned features are mentioned in [upcoming features](#upcoming-features).
+- Node.js 16+
+- Ollama (for local LLM)
+- SearxNG instance
 
 ## Installation
 
-There are mainly 2 ways of installing Perplexica - With Docker, Without Docker. Using Docker is highly recommended.
+1. Install Ollama:
+```bash
+# On macOS
+brew install ollama
+```
 
-### Getting Started with Docker (Recommended)
+2. Start Ollama:
+```bash
+# Start and enable on login
+brew services start ollama
 
-1. Ensure Docker is installed and running on your system.
-2. Clone the Perplexica repository:
+# Or run without auto-start
+/usr/local/opt/ollama/bin/ollama serve
+```
 
-   ```bash
-   git clone https://github.com/ItzCrazyKns/Perplexica.git
-   ```
+3. Pull the required model:
+```bash
+ollama pull mistral
+```
 
-3. After cloning, navigate to the directory containing the project files.
+4. Clone and set up the project:
+```bash
+git clone https://github.com/yourusername/bizsearch.git
+cd bizsearch
+npm install
+```
 
-4. Rename the `sample.config.toml` file to `config.toml`. For Docker setups, you need only fill in the following fields:
+5. Configure environment:
+```bash
+cp .env.example .env
+# Edit .env with your settings
+```
 
-   - `OPENAI`: Your OpenAI API key. **You only need to fill this if you wish to use OpenAI's models**.
-   - `OLLAMA`: Your Ollama API URL. You should enter it as `http://host.docker.internal:PORT_NUMBER`. If you installed Ollama on port 11434, use `http://host.docker.internal:11434`. For other ports, adjust accordingly. **You need to fill this if you wish to use Ollama's models instead of OpenAI's**.
-   - `GROQ`: Your Groq API key. **You only need to fill this if you wish to use Groq's hosted models**
+6. Start the application:
+```bash
+npm run dev
+```
 
-     **Note**: You can change these after starting Perplexica from the settings dialog.
+7. Open http://localhost:3000 in your browser
 
-   - `SIMILARITY_MEASURE`: The similarity measure to use (This is filled by default; you can leave it as is if you are unsure about it.)
+## Troubleshooting
 
-5. Ensure you are in the directory containing the `docker-compose.yaml` file and execute:
+If Ollama fails to start:
+```bash
+# Stop any existing instance
+brew services stop ollama
+# Wait a few seconds
+sleep 5
+# Start again
+brew services start ollama
+```
 
-   ```bash
-   docker compose up -d
-   ```
+To verify Ollama is running:
+```bash
+curl http://localhost:11434/api/version
+```
 
-6. Wait a few minutes for the setup to complete. You can access Perplexica at http://localhost:3000 in your web browser.
+## Features
 
-**Note**: After the containers are built, you can start Perplexica directly from Docker without having to open a terminal.
+- Business search with location filtering
+- Contact information extraction
+- AI-powered data validation
+- Clean, user-friendly interface
+- Service health monitoring
 
-### Non-Docker Installation
+## Configuration
 
-1. Clone the repository and rename the `sample.config.toml` file to `config.toml` in the root directory. Ensure you complete all required fields in this file.
-2. Rename the `.env.example` file to `.env` in the `ui` folder and fill in all necessary fields.
-3. After populating the configuration and environment files, run `npm i` in both the `ui` folder and the root directory.
-4. Install the dependencies and then execute `npm run build` in both the `ui` folder and the root directory.
-5. Finally, start both the frontend and the backend by running `npm run start` in both the `ui` folder and the root directory.
+Key environment variables:
+- `SEARXNG_URL`: Your SearxNG instance URL
+- `OLLAMA_URL`: Ollama API endpoint (default: http://localhost:11434)
+- `SUPABASE_URL`: Your Supabase project URL
+- `SUPABASE_ANON_KEY`: Your Supabase anonymous key
+- `CACHE_DURATION_DAYS`: How long to cache results (default: 7)
 
-**Note**: Using Docker is recommended as it simplifies the setup process, especially for managing environment variables and dependencies.
+## Supabase Setup
 
-## One-Click Deployment
+1. Create a new Supabase project
+2. Run the SQL commands in `db/init.sql` to create the cache table
+3. Copy your project URL and anon key to `.env`

+# Perplexica Search API Documentation
+
+## Overview
+
+Perplexica’s Search API makes it easy to use our AI-powered search engine. You can run different types of searches, pick the models you want to use, and get the most recent info. Follow the following headings to learn more about Perplexica's search API.
+
+## Endpoint
+
+### **POST** `http://localhost:3001/api/search`
+
+**Note**: Replace `3001` with any other port if you've changed the default PORT
+
+### Request
+
+The API accepts a JSON object in the request body, where you define the focus mode, chat models, embedding models, and your query.
+
+#### Request Body Structure
+
+```json
+{
+  "chatModel": {
+    "provider": "openai",
+    "model": "gpt-4o-mini"
+  },
+  "embeddingModel": {
+    "provider": "openai",
+    "model": "text-embedding-3-large"
+  },
+  "optimizationMode": "speed",
+  "focusMode": "webSearch",
+  "query": "What is Perplexica",
+  "history": [
+    ["human", "Hi, how are you?"],
+    ["assistant", "I am doing well, how can I help you today?"]
+  ]
+}
+```
+
+### Request Parameters
+
+- **`chatModel`** (object, optional): Defines the chat model to be used for the query. For model details you can send a GET request at `http://localhost:3001/api/models`. Make sure to use the key value (For example "gpt-4o-mini" instead of the display name "GPT 4 omni mini").
+
+  - `provider`: Specifies the provider for the chat model (e.g., `openai`, `ollama`).
+  - `model`: The specific model from the chosen provider (e.g., `gpt-4o-mini`).
+  - Optional fields for custom OpenAI configuration:
+    - `customOpenAIBaseURL`: If you’re using a custom OpenAI instance, provide the base URL.
+    - `customOpenAIKey`: The API key for a custom OpenAI instance.
+
+- **`embeddingModel`** (object, optional): Defines the embedding model for similarity-based searching. For model details you can send a GET request at `http://localhost:3001/api/models`. Make sure to use the key value (For example "text-embedding-3-large" instead of the display name "Text Embedding 3 Large").
+
+  - `provider`: The provider for the embedding model (e.g., `openai`).
+  - `model`: The specific embedding model (e.g., `text-embedding-3-large`).
+
+- **`focusMode`** (string, required): Specifies which focus mode to use. Available modes:
+
+  - `webSearch`, `academicSearch`, `writingAssistant`, `wolframAlphaSearch`, `youtubeSearch`, `redditSearch`.
+
+- **`optimizationMode`** (string, optional): Specifies the optimization mode to control the balance between performance and quality. Available modes:
+
+  - `speed`: Prioritize speed and return the fastest answer.
+  - `balanced`: Provide a balanced answer with good speed and reasonable quality.
+
+- **`query`** (string, required): The search query or question.
+
+- **`history`** (array, optional): An array of message pairs representing the conversation history. Each pair consists of a role (either 'human' or 'assistant') and the message content. This allows the system to use the context of the conversation to refine results. Example:
+
+  ```json
+  [
+    ["human", "What is Perplexica?"],
+    ["assistant", "Perplexica is an AI-powered search engine..."]
+  ]
+  ```
+
+### Response
+
+The response from the API includes both the final message and the sources used to generate that message.
+
+#### Example Response
+
+```json

+# Ethical Web Scraping Guidelines
+
+## Core Principles
+
+1. **Respect Robots.txt**
+   - Always check and honor robots.txt directives
+   - Cache robots.txt to reduce server load
+   - Default to conservative behavior when uncertain
+
+2. **Proper Identification**
+   - Use clear, identifiable User-Agent strings
+   - Provide contact information
+   - Be transparent about your purpose
+
+3. **Rate Limiting**
+   - Implement conservative rate limits
+   - Use exponential backoff for errors
+   - Distribute requests over time
+
+4. **Data Usage**
+   - Only collect publicly available business information
+   - Respect privacy and data protection laws
+   - Provide clear opt-out mechanisms
+   - Keep data accurate and up-to-date
+
+5. **Technical Considerations**
+   - Cache results to minimize requests
+   - Handle errors gracefully
+   - Monitor and log access patterns
+   - Use structured data when available
+
+## Implementation
+
+1. **Request Headers**
+```typescript
+const headers = {
+  'User-Agent': 'BizSearch/1.0 (+https://bizsearch.com/about)',
+  'Accept': 'text/html,application/xhtml+xml',
+  'From': 'contact@bizsearch.com'
+};
+```
+
+2. **Rate Limiting**
+```typescript
+const rateLimits = {
+  requestsPerMinute: 10,
+  requestsPerHour: 100,
+  requestsPerDomain: 20
+};
+```
+
+3. **Caching**
+```typescript
+const cacheSettings = {
+  ttl: 24 * 60 * 60, // 24 hours
+  maxSize: 1000 // entries
+};
+```
+
+## Opt-Out Process
+
+1. Business owners can opt-out by:
+   - Submitting a form on our website
+   - Emailing opt-out@bizsearch.com
+   - Adding a meta tag: `<meta name="bizsearch" content="noindex">`
+
+2. We honor opt-outs within:
+   - 24 hours for direct requests
+   - 72 hours for cached data
+
+## Legal Compliance
+
+1. **Data Protection**
+   - GDPR compliance for EU businesses
+   - CCPA compliance for California businesses
+   - Regular data audits and cleanup
+
+2. **Attribution**
+   - Clear source attribution
+   - Last-updated timestamps
+   - Data accuracy disclaimers
+
+## Best Practices
+
+1. **Before Scraping**
+   - Check robots.txt
+   - Verify site status
+   - Review terms of service
+   - Look for API alternatives
+
+2. **During Scraping**
+   - Monitor response codes
+   - Respect server hints
+   - Implement backoff strategies
+   - Log access patterns
+
+3. **After Scraping**
+   - Verify data accuracy
+   - Update cache entries
+   - Clean up old data
+   - Monitor opt-out requests

+# How does Perplexica work?
 
 Curious about how Perplexica works? Don't worry, we'll cover it here. Before we begin, make sure you've read about the architecture of Perplexica to ensure you understand what it's made up of. Haven't read it? You can read it [here](https://github.com/ItzCrazyKns/Perplexica/tree/master/docs/architecture/README.md).
 
 We'll understand how Perplexica works by taking an example of a scenario where a user asks: "How does an A.C. work?". We'll break down the process into steps to make it easier to understand. The steps are as follows:
 
 1. The message is sent via WS to the backend server where it invokes the chain. The chain will depend on your focus mode. For this example, let's assume we use the "webSearch" focus mode.
-2. The chain is now invoked; first, the message is passed to another chain where it first predicts (using the chat history and the question) whether there is a need for sources or searching the web. If there is, it will generate a query (in accordance with the chat history) for searching the web that we'll take up later. If not, the chain will end there, and then the answer generator chain, also known as the response generator, will be started.

If not, the chain will end there, and then the answer generator chain, also known as the response generator, will be started.
 3. The query returned by the first chain is passed to SearXNG to search the web for information.
 4. After the information is retrieved, it is based on keyword-based search. We then convert the information into embeddings and the query as well, then we perform a similarity search to find the most relevant sources to answer the query.
 5. After all this is done, the sources are passed to the response generator. This chain takes all the chat history, the query, and the sources. It generates a response that is streamed to the UI.
 
-### How are the answers cited?
+## How are the answers cited?
 
 The LLMs are prompted to do so. We've prompted them so well that they cite the answers themselves, and using some UI magic, we display it to the user.
 
-### Image and Video Search
+## Image and Video Search
 
 Image and video searches are conducted in a similar manner. A query is always generated first, then we search the web for images and videos that match the query. These results are then returned to the user.

-    Your responses should be medium to long in length be informative and relevant to the user's query. You can use markdowns to format your response. You should use bullet points to list the information. Make sure the answer is not short and is informative.
-    You have to cite the answer using [number] notation. You must cite the sentences with their relevent context number. You must cite each and every part of the answer so the user can know where the information is coming from.
-    Place these citations at the end of that particular sentence. You can cite the same sentence multiple times if it is relevant to the user's query like [number1][number2].
