Realtime News Usage

Use this file when a task needs recent facts, current public-opinion developments, event timelines, policy updates, or source verification.

Core Rule

The knowledge base is background context. It may be stale. Current facts require current material.

If bm25_search_news is available, use it for:

• Recent events.
• News facts.
• Public-opinion controversies.
• People or institution updates.
• Policy developments.
• Source checking.
• Timeline gaps.
• Conflicting claims.

How To Search

Start broad only when the issue is unclear:

core subject + controversy / latest / recent progress / public opinion

Then narrow each follow-up search using concrete entities or clues from previous results:

• Dates.
• Institutions.
• People.
• Places.
• Platform names.
• Event names.
• Official responses.
• Allegations or counter-claims.
• Specific policy names.

Do not repeat broad synonym searches when the first result set already provides bridge terms.

Combining News With Knowledge Files

Use this separation:

Knowledge files -> background, frameworks, prior patterns, actor context.
News results    -> current facts, dates, latest developments, source evidence.
Inference       -> your reasoning over both.

Do not treat news commentary as knowledge-base truth. Treat it as evidence that still needs source-quality assessment.

When To Continue Searching

Continue searching when:

• The timeline has gaps.
• Key actors are unclear.
• Sources conflict.
• Only one side is represented.
• The result set is old but the user asks about current status.
• A claim requires verification.

Output

When using news results:

• Link facts to visible Markdown links when URLs are available.
• Reuse the same link for repeated references to the same article.
• If no URL is available, name the title, source, and date.
• Keep news evidence separate from knowledge-base file references.
