介绍
# Perplexity Deep Search
AI 驱动的网络搜索，提供三种模式以满足不同深度的搜索需求。
## 快速开始
```bash # Quick search (sonar) - facts, summaries, current events {baseDir}/scripts/search.sh "latest AI news"
# Reasoning (sonar-reasoning-pro) - complex analysis, multi-step {baseDir}/scripts/search.sh --mode reason "compare React vs Vue for enterprise apps"
# Deep Research (sonar-deep-research) - full reports, exhaustive analysis {baseDir}/scripts/search.sh --mode research "market analysis of AI in healthcare 2025" ```
## 模式
| 模式 | 模型 | 最适合 | 成本 | |------|-------|----------|------| | `search` (默认) | `sonar-pro` | 快速事实、摘要、时事 | 低 | | `reason` | `sonar-reasoning-pro` | 复杂分析、对比、问题解决 | 中 | | `research` | `sonar-deep-research` | 深度报告、市场分析、文献综述 | 高 |
## 选项
| 标志 | 描述 | 默认值 | |------|-------------|---------| | `--mode` | `search`、`reason`、`research` | `search` | | `--recency` | `hour`、`day`、`week`、`month` | — | | `--domains` | 逗号分隔的域名过滤器 | — | | `--lang` | 语言代码 (`pt`、`en`、`es` 等) | — | | `--json` | 原始 JSON 输出 | off |
## 示例
```bash # Search with recency filter {baseDir}/scripts/search.sh --recency week "OpenAI latest announcements"
# Search restricted to specific domains {baseDir}/scripts/search.sh --domains "arxiv.org,nature.com" "transformer architecture advances"
# Search in Portuguese {baseDir}/scripts/search.sh --lang pt "inteligência artificial no Brasil"
# Deep research with JSON output {baseDir}/scripts/search.sh --mode research --json "enterprise AI adoption trends" ```
## API Key
设置 `PERPLEXITY_API_KEY` 环境变量，或将其存储在文件中： ```bash mkdir -p ~/.config/perplexity echo "your_key_here" > ~/.config/perplexity/api_key chmod 600 ~/.config/perplexity/api_key ```
脚本会优先检查环境变量，然后再回退到文件。
## 定价参考
- **Search (sonar-pro):** ~$0.01/次查询 - **Reasoning (sonar-reasoning-pro):** ~$0.02/次查询 - **Deep Research (sonar-deep-research):** ~$0.40/次查询（使用大量搜索 + 推理）
日常查询请使用 `search`。仅在真正需要详尽分析时才使用 `research`。
