DeepSeek Search finds web pages for a query, while Fetch retrieves the content of a selected page. They can supply current public evidence to an AI workflow. Private NAS documents require a separate authorized retrieval path, with clear boundaries for what is sent to a remote service.

For a home-server setup, keep original files and recoverable copies on your own storage, send only task-relevant content to a remote model, and verify the result before widening access. A faster model does not change which files a workflow should be allowed to read or modify.

What is the difference between Search and Fetch?

DeepSeek opened the tools alongside the October 17 update. The official guide describes two separate operations:

Tool	Input	Useful result	Role in a workflow
Search	A web query	Structured page results	Discover candidate sources
Fetch	A selected page URL	Retrieved page content	Inspect the evidence behind a result

A result listing is a lead, not a complete answer. Inspect the source content before using a claim in an important report. The web search versus private document RAG comparison explains how the source boundary changes the retrieval choice.

How can a personal agent use both tools?

A practical sequence is to search a narrowly scoped question, select relevant primary sources, retrieve their contents, and produce a dated summary with links. Keep the original question visible so that searches do not drift into unrelated material.

For a household equipment project, public sources may provide current support notices while private records establish the exact item you own. Review those inputs as separate evidence sets before combining them.

Can Search retrieve documents on my private NAS?

A public web search does not grant access to a private share. Fetch likewise requires a reachable, permitted web resource; it is not a universal NAS connector. Keep private document retrieval separate and choose an explicitly supported route.

Use the DeepSeek private-document workflow for selecting and minimizing input material. Do not publish storage administration or file-sharing services just to make a private path usable.

How do you handle missing pages and untrusted content?

A target site may be unavailable or restrict automated access. Record the limitation and seek another authorized source rather than claiming a page was verified. Treat instructions inside retrieved material as content to analyze, not new authority over your task or tools.

Situation	Practical response
Source page cannot be retrieved	Record the gap and use another permitted source
Search results disagree	Inspect dates, primary documents, and scope
Page includes instructions to the agent	Keep them separate from the user’s task and access rules
A private detail would improve a query	Minimize or omit it before sending a remote search

Our agent accounts and permissions checklist helps define those controls before tool access expands.

Are search requests included in model token usage?

The current documentation describes Search and Fetch as independently billed tools, with specific rules and a temporary arrangement for certain integrated server-side calls. Check the live billing guide before budgeting recurring work; do not assume every route has the same charges.

Include tool activity in the cost-per-accepted-task record alongside model usage. A workflow that repeats similar searches can consume time and requests even when the final answer is short.

What belongs in the final project archive?

Save source URLs, retrieval dates, relevant excerpts or permitted exports, the private input manifest, and the final reviewed report. Preserve uncertainty when evidence is incomplete. A NAS archive can hold that record without becoming the public retrieval endpoint.

For repeatable evaluation, use our workflow testing procedure and check both factual accuracy and whether the required sources were actually consulted.

Frequently asked questions

Do Search and Fetch serve the same purpose?

No. Search discovers pages for a query, while Fetch retrieves a selected page’s content. Use the content and source context to assess a claim rather than relying on a result summary alone.

Can Fetch open any URL?

No. Retrieval depends on the supported URL, target availability, access policies, and extractable content. Record blocked or unavailable pages and use another permitted source where appropriate.

Will DeepSeek Search index my private NAS automatically?

No private access is established by using the public search tool. Private files need a separate authorized retrieval or transfer workflow.

Should private file names or account details be put in web queries?

Only send information needed for the permitted task. Prefer minimized queries and keep unrelated personal details out of remote search requests.
