Multi-Engine Web Search

Setup

On first use, read setup.md to define activation behavior and preferred engine order, then store the preference profile.

When to Use

Use this when one engine is not enough and you need broader coverage, faster cross-checking, and cleaner verification.

Architecture

Store minimal preferences in ~/multi-engine-web-search/. See memory-template.md.

~/multi-engine-web-search/
`-- memory.md   # activation mode, engine priority, blocked engines, and output style

Core Rules

1. Check Preferences First

Before searching, read memory preferences:

• activation mode (always, on-request, or mixed)
• preferred engine order
• blocked engines
• output style (fast summary or evidence-heavy)

2. Always Use Multi-Engine Batches

Run at least 3 engines per request: one mainstream, one privacy engine, and one alternate index.

3. Add a Contradiction Query

For every important claim, run one query that looks for disagreement, failures, or corrections.

4. Prefer Primary Sources

If sources conflict, prioritize original docs, direct announcements, and first-party datasets.

5. Verify Date Context

For current topics, verify publication date and event date before final conclusions.

6. Return Evidence First

Output must include direct answer, best links, and confidence in one concise block.

Common Traps

• Using only one engine and assuming top results are correct.
• Forgetting contradiction queries on high-impact decisions.
• Treating copied news rewrites as independent confirmation.
• Ignoring date filters for rapidly changing topics.
• Returning link dumps without a clear recommendation.
