Introduction
# Web Search Pro
Multi-engine web search with full parameter control for AI agents. A precision supplement to OpenClaw's built-in `web_search` (Brave/Perplexity), providing domain filtering, deep search, news mode, date ranges, and content extraction that the built-in search does not support.
多引擎精细化网络搜索，为 AI Agent 设计。 作为 OpenClaw 内置 `web_search`（Brave/Perplexity）的精细化补充，提供域名过滤、 深度搜索、新闻模式、日期范围、内容提取等内置搜索不支持的能力。 配置一个或多个 API Key，自动选择最优引擎。
## Engines / 引擎
| Engine | Strengths | Free Tier | API Key Env | |--------|-----------|-----------|-------------| | **Tavily** | AI-optimized, best answer quality, full filters, extract | 1000/month | `TAVILY_API_KEY` | | **Exa** | Semantic/neural search, deep research | $10 credit | `EXA_API_KEY` | | **Serper** | Real Google SERP, best news coverage | 100/month | `SERPER_API_KEY` | | **SerpAPI** | Multi-engine (Google/Bing/Baidu/Yandex/DuckDuckGo) | 250/month | `SERPAPI_API_KEY` |
## Auto-Select Priority / 自动选择优先级
When `--engine` is not specified, the skill picks the best available engine:
| Query Type | Priority | Reason | |------------|----------|--------| | Default | Tavily > Exa > Serper > SerpAPI | Tavily has best AI answer + full filters | | `--deep` | Tavily > Exa | Both have dedicated deep search modes | | `--news` | Serper > Tavily | Google News has widest coverage | | `--include-domains` | Tavily > Exa > Serper > SerpAPI | Tavily/Exa have native domain filters | | `--search-engine baidu` | SerpAPI | Only SerpAPI supports Baidu/Yandex | | Chinese queries | SerpAPI (Baidu) > Serper | Baidu has better Chinese results |
## Search / 搜索
```bash # Basic search (auto-select engine) node {baseDir}/scripts/search.mjs "query"
# Force specific engine node {baseDir}/scripts/search.mjs "query" --engine tavily
# Domain filtering (only search specific sites) node {baseDir}/scripts/search.mjs "query" --include-domains "github.com,stackoverflow.com"
# Exclude domains node {baseDir}/scripts/search.mjs "query" --exclude-domains "pinterest.com,quora.com"
# Date range (absolute) node {baseDir}/scripts/search.mjs "query" --from 2026-01-01 --to 2026-02-09
# Time range (relative) node {baseDir}/scripts/search.mjs "query" --time-range week
# Deep/advanced search node {baseDir}/scripts/search.mjs "query" --deep
# News search node {baseDir}/scripts/search.mjs "query" --news --days 7
# Multi-engine: Baidu search node {baseDir}/scripts/search.mjs "query" --engine serpapi --search-engine baidu
# More results node {baseDir}/scripts/search.mjs "query" -n 10
# JSON output (for programmatic use) node {baseDir}/scripts/search.mjs "query" --json ```
## Extract / 内容提取
Extract readable content from URLs (Tavily Extract or Exa livecrawl):
```bash node {baseDir}/scripts/extract.mjs "https://example.com/article" node {baseDir}/scripts/extract.mjs "url1" "url2" "url3" node {baseDir}/scripts/extract.mjs "url" --engine exa node {baseDir}/scripts/extract.mjs "url" --json ```
## All Options / 全部参数
| Option | Description | Engines | |--------|-------------|---------| | `--engine <name>` | Force engine: tavily\|exa\|serper\|serpapi | all | | `-n <count>` | Number of results (default: 5) | all | | `--deep` | Deep/advanced search mode | tavily, exa | | `--news` | News search mode | tavily, serper, serpapi | | `--days <n>` | Limit news to last N days | tavily | | `--include-domains <d,...>` | Only search these domains | all (native: tavily, exa) | | `--exclude-domains <d,...>` | Exclude these domains | all (native: tavily, exa) | | `--time-range <range>` | day\|week\|month\|year | all | | `--from <YYYY-MM-DD>` | Results after this date | all | | `--to <YYYY-MM-DD>` | Results before this date | all | | `--search-engine <name>` | SerpAPI sub-engine: google\|bing\|baidu\|yandex\|duckduckgo | serpapi | | `--country <code>` | Country code (us, cn, de...) | serper, serpapi | | `--lang <code>` | Language code (en, zh, de...) | serper, serpapi | | `--json` | Raw JSON output | all |
## Setup / 配置
Add API keys to your environment (e.g., `~/.openclaw/.env`):
```bash # Configure at least one (recommended: Tavily) TAVILY_API_KEY=tvly-xxxxx # https://tavily.com (1000 free/month) EXA_API_KEY=exa-xxxxx # https://exa.ai ($10 free credit) SERPER_API_KEY=xxxxx # https://serper.dev (100 free/month) SERPAPI_API_KEY=xxxxx # https://serpapi.com (250 free/month) ```
## Notes / 说明
- At least one API key must be configured - Domain filtering via `--include-domains`/`--exclude-domains` works natively on Tavily and Exa; on Serper/SerpAPI it's implemented via `site:` query operators - `--deep` mode uses more API credits (Tavily: 2x, Exa: varies) - Extract only works with Tavily and Exa - All output is Markdown-formatted for AI agent consumption; use `--json` for programmatic access
