alibabacloud-iqs-search#

Prerequisites#

• Node.js >= 18.0.0 (scripts use native fetch API, no external npm dependencies)

When to Use#

• User asks for current/recent information
• User provides a URL to read
• Need to verify facts or get real-time data
• Research tasks requiring multiple sources

Decision Tree#

Step 1: Determine Operation Type#

• If user provides a URL → Use readpage
• If user asks a question needing web info → Use search

Step 2: For Search Operations#

Follow the best practices to determine parameter values. Use default values when uncertain:

• engineType
• timeRange
• contents

Step 3: For Page Reading#

Follow the best practices to determine parameter values. Use default values when uncertain:

• format
• extractArticle
• stealthMode

CRITICAL: Execution Method#

You MUST execute the scripts via bash command (e.g., node scripts/search.mjs ... or node scripts/readpage.mjs ...). Do NOT use your built-in web_search, WebFetch, or any other internal tools as substitutes. If the script fails, retry or report the error — do NOT fall back to built-in tools.

Parameters & Best Practices#

Search Parameters#

Search Best Practices

1. Query Optimization ( --query)

• Keep queries concise (< 30 chars for best results)
• Use specific keywords, avoid stop words
• For news: include time context in query

2. Engine Selection ( --engineType)

The four engines differ significantly in latency, recall depth, content length, and cost. Pick the cheapest engine that meets the task — do NOT default to Deep; it is ~10× slower and 50× more expensive than the standard engine.

Decision rules:

• Default → LiteAdvanced: low latency + semantic search + snippet covers most Agent needs without needing extra mainText fetches.

• Choose Generic when: the query is short and clearly informational (news, weather, simple facts), or when minimizing cost matters; also the only engine honoring city / ip for scene results (weather etc.).

• Choose Deep ONLY when: the question is multi-hop / complex reasoning (FRAMES/BrowseComp-style), OR you need very long mainText (≤50000 characters, ~16× longer than other engines) for downstream LLM reasoning.

  • ⚠️ Avoid Deep for: real-time chat, simple lookups, high-QPS scenarios — latency (~6s) and cost (50×) are prohibitive.

3. Time Range Selection ( --timeRange)

• NoLimit: Default when uncertain - engine optimizes based on query relevance
• OneDay: Today only
• OneWeek: Last 7 days
• OneMonth: Last 30 days
• OneYear: Last 365 days

4. Content Return ( --contents)

• mainText: Return full main text content - Use when detailed information is needed, such as technical documentation, research reports, or in-depth articles
• summary: Return concise summary only - Use when a quick overview is sufficient, or when the page content is too large and token reduction is needed

5. Result Count ( --numResults)

• Control number of results returned (default: 10, range: 1-10)

ReadPage Best Practices

1. Format Selection ( --format)

• markdown: Best for articles, preserves structure (default)
• text: Best for data extraction
• html: When structure analysis needed

2. Article Extraction ( --extractArticle)

• Enable for: blogs, news articles
• Disable for: product pages, directories

3. Handling Failures ( --timeout, --stealth)

• If timeout: Retry with increased --timeout value
• If blocked: Enable --stealth 1
• If still fails: Report to user

Command Line Usage#

Search Examples#

Basic Search

bash

node scripts/search.mjs --query "量子计算原理" --engineType LiteAdvanced

Real-time Information Search

bash

node scripts/search.mjs --query "最新金融政策" --engineType Generic --timeRange OneWeek

Search with Results Limit

bash

node scripts/search.mjs --query "www.aliyun.com" --engineType LiteAdvanced --numResults 3

Search with Full Content

bash

node scripts/search.mjs --query "AI 法案" --engineType LiteAdvanced --contents mainText

Search with Summary Only

bash

node scripts/search.mjs --query "人工智能行业年度报告" --engineType LiteAdvanced --contents summary

Deep Research Search (complex multi-hop / long mainText)

bash

# Returns up to 50000-char mainText per result; latency ~6s. Default timeout auto-bumps to 60s for Deep.
node scripts/search.mjs --query "对比 GPT-5 与 Claude Opus 4.7 的代码能力差异" --engineType Deep --numResults 5 --contents mainText

ReadPage Examples#

Page Reading with Markdown Format

bash

node scripts/readpage.mjs --url "https://example.com/article" --format markdown --extractArticle true

Page Reading with Plain Text Format

bash

node scripts/readpage.mjs --url "https://example.com/article" --format text --timeout 60000

Page Reading with Stealth Mode

bash

node scripts/readpage.mjs --url "https://example.com/article" --format markdown --stealth 1 --extractArticle true

Output Verification#

After executing any search.mjs or readpage.mjs command:

1. Check the exit code: If non-zero, the command failed — do not claim success.
2. Verify output exists: If you saved results to a file, run ls -la <filepath> and head -20 <filepath> to confirm the file exists and contains valid data.
3. Never fabricate results: If the command failed or returned an error, report the failure honestly. Do not generate content from your own knowledge and present it as search results.

Error Handling#

ALIYUN_IQS_API_KEY Configuration Error#

If the script returns an error about missing API key:

1. STOP the current task immediately. Do NOT fall back to built-in tools (WebFetch, web_search, curl, etc.) as substitutes.

2. Report the error to the user and ask the user to configure the API key:

3. Retry the task with following instruction: Method 1: Environment Variable

bash

export ALIYUN_IQS_API_KEY="your-api-key"

Method 2: Configuration File Create or edit ~/.alibabacloud/iqs/env:

bash

ALIYUN_IQS_API_KEY=your-api-key
