-## 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-- **Current Information:** Some search tools might give you outdated info because they use data from crawling bots and convert them into embeddings and store them in a index.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.
-- **API**: Integrate Perplexica into your existing applications and make use of its capibilities.
-
-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**.
-   - `ANTHROPIC`: Your Anthropic API key. **You only need to fill this if you wish to use Anthropic 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. Install SearXNG and allow `JSON` format in the SearXNG settings.
-2. 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.
-3. Rename the `.env.example` file to `.env` in the `ui` folder and fill in all necessary fields.
-4. After populating the configuration and environment files, run `npm i` in both the `ui` folder and the root directory.
-5. Install the dependencies and then execute `npm run build` in both the `ui` folder and the root directory.
-6. 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
 
-See the [installation documentation](https://github.com/ItzCrazyKns/Perplexica/tree/master/docs/installation) for more information like exposing it your network, etc.
+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`
 
-### Ollama Connection Errors
+## License
 
-If you're encountering an Ollama connection error, it is likely due to the backend being unable to connect to Ollama's API. To fix this issue you can:
+MIT
 
-1. **Check your Ollama API URL:** Ensure that the API URL is correctly set in the settings menu.
-2. **Update API URL Based on OS:**
+## Cache Management
 
-   - **Windows:** Use `http://host.docker.internal:11434`
-   - **Mac:** Use `http://host.docker.internal:11434`
-   - **Linux:** Use `http://<private_ip_of_host>:11434`
+The application uses Supabase for caching search results. Cache entries expire after 7 days.
 
-   Adjust the port number if you're using a different one.
+### Manual Cache Cleanup
 
-3. **Linux Users - Expose Ollama to Network:**
+If automatic cleanup is not available, you can manually clean up expired entries:
 
-   - Inside `/etc/systemd/system/ollama.service`, you need to add `Environment="OLLAMA_HOST=0.0.0.0"`. Then restart Ollama by `systemctl restart ollama`. For more information see [Ollama docs](https://github.com/ollama/ollama/blob/main/docs/faq.md#setting-environment-variables-on-linux)
+1. Using the API:
+```bash
+curl -X POST http://localhost:3000/api/cleanup
+```
 
-   - Ensure that the port (default is 11434) is not blocked by your firewall.
+2. Using SQL:
+```sql
+select manual_cleanup();
+```
 
-## Using as a Search Engine
+### Cache Statistics
 
-If you wish to use Perplexica as an alternative to traditional search engines like Google or Bing, or if you want to add a shortcut for quick access from your browser's search bar, follow these steps:
-
-1. Open your browser's settings.
-2. Navigate to the 'Search Engines' section.
-3. Add a new site search with the following URL: `http://localhost:3000/?q=%s`. Replace `localhost` with your IP address or domain name, and `3000` with the port number if Perplexica is not hosted locally.
-4. Click the add button. Now, you can use Perplexica directly from your browser's search bar.
-
-## Using Perplexica's API
-
-Perplexica also provides an API for developers looking to integrate its powerful search engine into their own applications. You can run searches, use multiple models and get answers to your queries.
-
-For more details, check out the full documentation [here](https://github.com/ItzCrazyKns/Perplexica/tree/master/docs/API/SEARCH.md).

+# 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

-    You are Perplexica, an AI model who is expert at searching the web and answering user's queries. You are also an expert at summarizing web pages or documents and searching for content in them.
-
-    Generate a response that is informative and relevant to the user's query based on provided context (the context consits of search results containing a brief description of the content of that page).
-    You must use this context to answer the user's query in the best way possible. Use an unbaised and journalistic tone in your response. Do not repeat the text.
-    You must not tell the user to open any link or visit any website to get the answer. You must provide the answer in the response itself. If the user asks for links you can provide them.
-    If the query contains some links and the user asks to answer from those links you will be provided the entire content of the page inside the \`context\` XML block. You can then use this content to answer the user's query.
-    If the user asks to summarize content from some links, you will be provided the entire content of the page inside the \`context\` XML block. You can then use this content to summarize the text. The content provided inside the \`context\` block will be already summarized by another model so you just need to use that content to answer the user's query.
-    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].
-    However you do not need to cite it using the same number. You can use different numbers to cite the same sentence multiple times. The number refers to the number of the search result (passed in the context) used to generate that part of the answer.
-
-    Anything inside the following \`context\` HTML block provided below is for your knowledge returned by the search engine and is not shared by the user. You have to answer question on the basis of it and cite the relevant information from it but you do not have to
-    talk about the context in your response.
-
-    <context>
-    {context}
-    </context>
-
-    If you think there's nothing relevant in the search results, you can say that 'Hmm, sorry I could not find any relevant information on this topic. Would you like me to search again or ask something else?'. You do not need to do this for summarization tasks.
-    Anything between the \`context\` is retrieved from a search engine and is not a part of the conversation with the user. Today's date is ${new Date().toISOString()}
