 # Web Search Tool (`web_search`)
 
-This document describes the `web_search` tool.
+This document describes the `web_search` tool for performing web searches using multiple providers.
 
 ## Description
 
-Use `web_search` to perform a web search using the Tavily API. The tool returns a concise answer with sources when possible.
+Use `web_search` to perform a web search and get information from the internet. The tool supports multiple search providers and returns a concise answer with source citations when available.
+
+### Supported Providers
+
+1. **DashScope** (Official, Free) - Automatically available for Qwen OAuth users (200 requests/minute, 2000 requests/day)
+2. **Tavily** - High-quality search API with built-in answer generation
+3. **Google Custom Search** - Google's Custom Search JSON API
 
 ### Arguments
 
-`web_search` takes one argument:
+`web_search` takes two arguments:
 
-- `query` (string, required): The search query.
+- `query` (string, required): The search query
+- `provider` (string, optional): Specific provider to use ("dashscope", "tavily", "google")
+  - If not specified, uses the default provider from configuration
 
-## How to use `web_search`
+## Configuration
 
-`web_search` calls the Tavily API directly. You must configure the `TAVILY_API_KEY` through one of the following methods:
+### Method 1: Settings File (Recommended)
 
-1. **Settings file**: Add `"tavilyApiKey": "your-key-here"` to your `settings.json`
-2. **Environment variable**: Set `TAVILY_API_KEY` in your environment or `.env` file
-3. **Command line**: Use `--tavily-api-key your-key-here` when running the CLI
+Add to your `settings.json`:
 
-If the key is not configured, the tool will be disabled and skipped.
-
-Usage:
-
-```
-web_search(query="Your query goes here.")
+```json
+{
+  "webSearch": {
+    "provider": [
+      { "type": "dashscope" },
+      { "type": "tavily", "apiKey": "tvly-xxxxx" },
+      {
+        "type": "google",
+        "apiKey": "your-google-api-key",
+        "searchEngineId": "your-search-engine-id"
+      }
+    ],
+    "default": "dashscope"
+  }
+}
 ```
 
-## `web_search` examples
+**Notes:**
 
-Get information on a topic:
+- DashScope doesn't require an API key (official, free service)
+- **Qwen OAuth users:** DashScope is automatically added to your provider list, even if not explicitly configured
+- Configure additional providers (Tavily, Google) if you want to use them alongside DashScope
+- Set `default` to specify which provider to use by default (if not set, priority order: Tavily > Google > DashScope)
 
-```
-web_search(query="latest advancements in AI-powered code generation")
+### Method 2: Environment Variables
+
+Set environment variables in your shell or `.env` file:
+
+```bash
+# Tavily
+export TAVILY_API_KEY="tvly-xxxxx"
+
+# Google
+export GOOGLE_API_KEY="your-api-key"
+export GOOGLE_SEARCH_ENGINE_ID="your-engine-id"
 ```
 
-## Important notes
+### Method 3: Command Line Arguments
 
-- **Response returned:** The `web_search` tool returns a concise answer when available, with a list of source links.
-- **Citations:** Source links are appended as a numbered list.
-- **API key:** Configure `TAVILY_API_KEY` via settings.json, environment variables, .env files, or command line arguments. If not configured, the tool is not registered.
+Pass API keys when running Qwen Code:
+
+```bash
+# Tavily
+qwen --tavily-api-key tvly-xxxxx
+
+# Google
+qwen --google-api-key your-key --google-search-engine-id your-id
+
+# Specify default provider
+qwen --web-search-default tavily
+```
+
+### Backward Compatibility (Deprecated)
+
+⚠️ **DEPRECATED:** The legacy `tavilyApiKey` configuration is still supported for backward compatibility but is deprecated:
+
+```json
+{
+  "advanced": {
+    "tavilyApiKey": "tvly-xxxxx" // ⚠️ Deprecated
+  }
+}
+```
+
+**Important:** This configuration is deprecated and will be removed in a future version. Please migrate to the new `webSearch` configuration format shown above. The old configuration will automatically configure Tavily as a provider, but we strongly recommend updating your configuration.
+
+## Disabling Web Search
+
+If you want to disable the web search functionality, you can exclude the `web_search` tool in your `settings.json`:
+
+```json
+{
+  "tools": {
+    "exclude": ["web_search"]
+  }
+}
+```
+
+**Note:** This setting requires a restart of Qwen Code to take effect. Once disabled, the `web_search` tool will not be available to the model, even if web search providers are configured.
+
+## Usage Examples
+
+### Basic search (using default provider)
+
+```
+web_search(query="latest advancements in AI")
+```
+
+### Search with specific provider
+
+```
+web_search(query="latest advancements in AI", provider="tavily")
+```
+
+### Real-world examples
+
+```
+web_search(query="weather in San Francisco today")
+web_search(query="latest Node.js LTS version", provider="google")
+web_search(query="best practices for React 19", provider="dashscope")
+```
+
+## Provider Details
+
+### DashScope (Official)
+
+- **Cost:** Free
+- **Authentication:** Automatically available when using Qwen OAuth authentication
+- **Configuration:** No API key required, automatically added to provider list for Qwen OAuth users
+- **Quota:** 200 requests/minute, 2000 requests/day
+- **Best for:** General queries, always available as fallback for Qwen OAuth users
+- **Auto-registration:** If you're using Qwen OAuth, DashScope is automatically added to your provider list even if you don't configure it explicitly
+
+### Tavily
+
+- **Cost:** Requires API key (paid service with free tier)
+- **Sign up:** https://tavily.com
+- **Features:** High-quality results with AI-generated answers
+- **Best for:** Research, comprehensive answers with citations
+
+### Google Custom Search
+
+- **Cost:** Free tier available (100 queries/day)
+- **Setup:**
+  1. Enable Custom Search API in Google Cloud Console
+  2. Create a Custom Search Engine at https://programmablesearchengine.google.com
+- **Features:** Google's search quality
+- **Best for:** Specific, factual queries
+
+## Important Notes
+
+- **Response format:** Returns a concise answer with numbered source citations
+- **Citations:** Source links are appended as a numbered list: [1], [2], etc.
+- **Multiple providers:** If one provider fails, manually specify another using the `provider` parameter
+- **DashScope availability:** Automatically available for Qwen OAuth users, no configuration needed
+- **Default provider selection:** The system automatically selects a default provider based on availability:
+  1. Your explicit `default` configuration (highest priority)
+  2. CLI argument `--web-search-default`
+  3. First available provider by priority: Tavily > Google > DashScope
+
+## Troubleshooting
+
+**Tool not available?**
+
+- **For Qwen OAuth users:** The tool is automatically registered with DashScope provider, no configuration needed
+- **For other authentication types:** Ensure at least one provider (Tavily or Google) is configured
+- For Tavily/Google: Verify your API keys are correct
+
+**Provider-specific errors?**
+
+- Use the `provider` parameter to try a different search provider
+- Check your API quotas and rate limits
+- Verify API keys are properly set in configuration
+
+**Need help?**
+
+- Check your configuration: Run `qwen` and use the settings dialog
+- View your current settings in `~/.qwen-code/settings.json` (macOS/Linux) or `%USERPROFILE%\.qwen-code\settings.json` (Windows)

 - **Plan:** After understanding the user's request, create an initial plan based on your existing knowledge and any immediately obvious context. Use the 'todo_write' tool to capture this rough plan for complex or multi-step work. Don't wait for complete understanding - start with what you know.
-- **Implement:** Begin implementing the plan while gathering additional context as needed. Use 'search_file_content', 'glob', 'read_file', and 'read_many_files' tools strategically when you encounter specific unknowns during implementation. Use the available tools (e.g., 'edit', 'write_file' 'run_shell_command' ...) to act on the plan, strictly adhering to the project's established conventions (detailed under 'Core Mandates').

 - **Plan:** After understanding the user's request, create an initial plan based on your existing knowledge and any immediately obvious context. Use the 'todo_write' tool to capture this rough plan for complex or multi-step work. Don't wait for complete understanding - start with what you know.
-- **Implement:** Begin implementing the plan while gathering additional context as needed. Use 'search_file_content', 'glob', 'read_file', and 'read_many_files' tools strategically when you encounter specific unknowns during implementation. Use the available tools (e.g., 'edit', 'write_file' 'run_shell_command' ...) to act on the plan, strictly adhering to the project's established conventions (detailed under 'Core Mandates').
+- **Implement:** Begin implementing the plan while gathering additional context as needed. Use 'grep_search', 'glob', 'read_file', and 'read_many_files' tools strategically when you encounter specific unknowns during implementation. Use the available tools (e.g., 'edit', 'write_file' 'run_shell_command' ...) to act on the plan, strictly adhering to the project's established conventions (detailed under 'Core Mandates').
 - **Adapt:** As you discover new information or encounter obstacles, update your plan and todos accordingly. Mark todos as in_progress when starting and completed when finishing each task. Add new todos if the scope expands. Refine your approach based on what you learn.
 - **Verify (Tests):** If applicable and feasible, verify the changes using the project's testing procedures. Identify the correct test commands and frameworks by examining 'README' files, build/package configuration (e.g., 'package.json'), or existing test execution patterns. NEVER assume standard test commands.
 - **Verify (Standards):** VERY IMPORTANT: After making code changes, execute the project-specific build, linting and type-checking commands (e.g., 'tsc', 'npm run lint', 'ruff check .') that you have identified for this project (or obtained from the user). This ensures code quality and adherence to standards. If unsure about these commands, you can ask the user if they'd like you to run them and if so how to.
