 Search Question and Answering is the task of using Search Engine (e.g. Google Search) to improve the QA quality. Large language models have limitation on answering real-time information or specific details because they are limited to prior training data. A search engine can make up this advantage. By using a search engine, this SearchQnA service will firstly look up the relevant source web pages and feed them as context to the LLMs, so LLMs can use those context to compose answers more precisely.

+    npm install -g n && \
+    n stable && \
+    hash -r && \
+    npm install -g npm@latest

+curl -sL https://rpm.nodesource.com/setup_20.x | sudo bash -
+sudo yum install -y nodejs
+```
+
+Update the `BACKEND_BASE_URL` environment variable in the `.env` file by replacing the IP address '127.0.0.1' with the actual IP address.
+
+Run the following command to install the required dependencies:
+
+```bash
+npm install
+```
+
+Start the development server by executing the following command:
+
+```bash
+nohup npm run dev &
+```
+
+This will initiate the frontend service and launch the application.

+<h2>🧐 Features</h2>
+
+Here're some of the project's features:
+
+- Start a Text Chat：Initiate a text chat with the ability to input written conversations, where the dialogue content can also be customized based on uploaded files.
+- Upload File: The choice between uploading locally or copying a remote link. Chat according to uploaded knowledge base.
+- Clear: Clear the record of the current dialog box without retaining the contents of the dialog box.
+- Chat history: Historical chat records can still be retained after refreshing, making it easier for users to view the context.
+- Scroll to Bottom / Top: The chat automatically slides to the bottom. Users can also click the top icon to slide to the top of the chat record.
+- End to End Time: Shows the time spent on the current conversation.
+
+<h2>🛠️ Get it Running:</h2>
+
+1. Clone the repo.
+
+2. cd command to the current folder.
+
+3. Modify the required .env variables.
+   ```
+   BACKEND_BASE_URL = ''
+   ```
+4. Execute `npm install` to install the corresponding dependencies.
+
+5. Execute `npm run dev` in both environments
