domain

Not specified by the original author.

TL;DR

Yes. Parallel's Search API (and the Task API) accepts a sourcepolicy object with includedomains and excludedomains lists: includedomains is an allowlist, only sources from those domains appear; exclude_domains is a blocklist, sources from those domains never appear. The two lists combined cannot exceed 200 domains, and an apex domain like example.com automatically covers its subdomains. The parallel-cli exposes the same controls as repeatable --include-domains and --exclude-domains flags.

can parallel search include or exclude specific domains from results

Steps

1. Decide whether you need a hard allowlist or a blocklist. Use includedomains when you know exactly which sources count; use excludedomains when you only want to cut noise like forums or social sites. Expected: you can write down the domain list and say which of the two it is.

2. Send the policy inside the search request body as source_policy. Get an API key from the Parallel platform console and send it in the x-api-key request header. Expected: the API returns a 200 with a results array, not a validation error.

3. Check that the returned URLs honor the policy. Scan the url fields of the results. Expected: with includedomains, every result URL belongs to a listed domain; with excludedomains, no result URL belongs to a blocked one.

4. If results look thin with an allowlist, widen it instead of dropping the policy. Small allowlists can return zero results on niche queries. Expected: adding one or two more domains brings results back without losing focus.

5. For quick checks use the CLI flags instead of the raw API: parallel-cli search with --include-domains or --exclude-domains, repeatable per domain. Expected: the CLI returns JSON results scoped to the domains you passed.

curl -s -X POST "https://api.parallel.ai/v1beta/search" \
  -H "Content-Type: application/json" \
  -H "parallel-beta: search-extract-2025-10-10" \
  -d '{"objective": "React hooks best practices", "max_results": 5, "source_policy": {"include_domains": ["react.dev", "github.com"]}}'

To block domains instead:

curl -s -X POST "https://api.parallel.ai/v1beta/search" \
  -H "Content-Type: application/json" \
  -H "parallel-beta: search-extract-2025-10-10" \
  -d '{"objective": "startup funding news", "max_results": 5, "source_policy": {"exclude_domains": ["reddit.com", "x.com"]}}'

Use this when

• An agent needs search results limited to trusted sources like docs sites or publishers
• You want to block noisy or low-quality domains from agent research results
• You are building a domain-scoped research flow on the Parallel Search or Task API
• A query keeps returning forums and you want them gone without rewriting the query

Not for this skill when

• You only want to prefer certain sources, not hard-filter them (steer that in the objective text, e.g. prefer official documentation)
• You are using a different search provider (this policy object is Parallel-specific)
• You need more than 200 domains combined (the API rejects it; split into multiple searches)
• You need per-URL filtering rather than per-domain filtering (filter client-side after the call)

Variant phrasings

parallel search api include domains

Pass "source_policy": {"include_domains": ["arxiv.org", "nature.com"]} in the request body. Only those domains appear.

parallel search exclude domains

Pass "source_policy": {"exclude_domains": ["reddit.com"]} in the request body. Those domains never appear.

parallel-cli domain flags

parallel-cli search "your query" --include-domains react.dev --include-domains github.com --json or the --exclude-domains mirror. Flags are repeatable, up to 10 per search on the CLI.

Why it happens

Agent search calls often drown in forum threads and SEO filler when the agent actually wants docs or primary sources. Parallel answers that with a hard domain policy evaluated server-side: the allowlist version narrows the corpus before ranking, the blocklist version removes domains after retrieval. The 200-domain combined cap keeps the policy cheap to evaluate, and apex-domain matching means you list example.com once instead of every subdomain.

Edge cases

• includedomains plus excludedomains in one request is allowed; the 200 cap counts both lists together and exceeding it raises a validation error.
• Listing an apex domain covers www and all subdomains automatically, so do not list each subdomain separately.
• Overly narrow allowlists return empty results on niche topics. That is the policy working, not a bug; widen the list.
• Domain filtering is exact on the registered domain. Internationalized or lookalike domains are treated as different domains.
• afterdate and other filters combine with sourcepolicy; they narrow independently, so stacking many filters can also empty the results.

TL;DR

Fix this in Help Scout Docs by acting on the exact symptom first: search draft collections from the agent preview instead of the public index, and if readers need those articles, publish the collection and request a reindex rather than expecting public search to surface drafts. Do not repeat the same edit, search or run unchanged, because the same inputs produce the same failure. Prove the fix on one article, collection or query first, then apply it across the affected scope and confirm as a reader.

Help Scout Docs search ignores articles inside draft collections

Use this when

• Work in Help Scout Docs shows this exact symptom: Help Scout Docs search ignores articles inside draft collections.
• The same symptom repeats after a retry with unchanged inputs.
• Readers or support agents are blocked until this item is corrected.

Not for this skill when

• The help center platform itself is down or returning outage notices. Resolve that first, then return here if this symptom remains.
• The content is correct and you only want a style or tone rewrite. That is an editorial pass, not this fix.

Steps

1. Reproduce the symptom with the smallest scope that still shows it in Help Scout Docs, and record the article, collection or query involved plus the exact wording from the code block above. Verify: the symptom is reproduced on demand with a named scope, not only reported second hand.
2. Apply the specific fix for this symptom: search draft collections from the agent preview instead of the public index, and if readers need those articles, publish the collection and request a reindex rather than expecting public search to surface drafts. Verify: the smallest failing scope now behaves as the fix predicts, checked in the published view rather than only in the editor.
3. Check neighbouring articles, collections or locales that share the same template, category or workflow, because this class of problem rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Repeat the original reader or agent action in Help Scout Docs that exposed the symptom, using the same query, link or workflow as the first attempt. Verify: the action completes and the original symptom does not appear.
5. Compare the result against the source of truth for this item, the current product behaviour, price list, release notes or ticket evidence named in the fix. Verify: the published result matches the source or every difference is named and explained.
6. Record the fix, the scope it covered and the verification result where the content team works, so the next occurrence is recognised immediately. Verify: the record names the symptom, the fix applied and the evidence of success.

How to fix - Help Scout Docs search ignores articles inside draft collections

The how to phrasing for the same problem in Help Scout Docs. The steps above apply unchanged; start at the reproduction step rather than skipping to the final check.

Help Scout Docs troubleshooting for this symptom

The symptom first phrasing used when the full message is hidden. Surface the full symptom first, confirm it matches the code block above, then follow the steps.

Why it happens

Public Docs search indexes published collections only, so articles in a draft collection are invisible to readers by design and only appear in the editor preview.

Edge cases

• The symptom appears in one locale, collection or audience view only. Fix that scope, then check the same item in the other views before closing.
• A cached or indexed copy keeps showing the old state after the fix. Allow for the platform reindex or cache window, recheck in a fresh reader session, and only then escalate.
• Two items have near identical titles. Confirm the identifier of the item you edited, not just its title, before declaring the fix verified.

Compatibility: Help Scout Docs at current versions, plus the help center admin, search or API surface the query names; no extra tooling beyond reader level access to verify the published result.

TL;DR

Restrict Parallel web search to an approved domain list by setting source_policy.include_domains to your allowlist. Only matching sources are returned. On the Search API, nest it under advanced_settings.source_policy; on the Search MCP, pin it as a connection-level override (URL query parameter or config header). Leave exclude_domains out of the same request: it is silently ignored whenever include_domains is non-empty.

Search: parallel search source policy approved domains

Search API

curl https://api.parallel.ai/v1/search \
  -H "Content-Type: application/json" \
  -H "x-api-key value $PARALLEL_API_KEY" \
  -d '{
    "objective": "What did the Parallel changelog announce this month?",
    "search_queries": ["Parallel changelog October"],
    "advanced_settings": {
      "source_policy": {
        "include_domains": ["parallel.ai", "docs.parallel.ai"]
      }
    }
  }'

Expected output: every returned result's URL lives on parallel.ai or docs.parallel.ai (an apex entry like parallel.ai automatically covers its subdomains).

Task API

Put source_policy at the top level of the task request:

curl -X POST "https://api.parallel.ai/v1/tasks/runs" \
  -H "x-api-key value $PARALLEL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "input": "Summarize the Parallel changelog this month",
    "processor": "core",
    "source_policy": {
      "include_domains": ["parallel.ai"]
    }
  }'

Search MCP (connection override)

Authenticated MCP connections can pin the same policy so it applies to every web_search on the connection. Append list fields to the server URL, comma-separated or repeated:

https://search.parallel.ai/mcp?advanced_settings.source_policy.include_domains=parallel.ai,docs.parallel.ai

Or send a config header (useful for larger nested configs) matching the Search API request shape:

{
  "advanced_settings": {
    "source_policy": {
      "include_domains": ["parallel.ai", "docs.parallel.ai"]
    }
  }
}

Expected output: the MCP handshake succeeds (a 400 at connect time means a bad field, bad mode, or malformed header JSON), and every web_search call returns only the allowed domains.

Steps

1. List your approved domains in apex form, one per entry: parallel.ai covers www.parallel.ai, docs.parallel.ai, and deeper subdomains. Never add schemes, ports, query strings, or fragments.
2. On the Search API, set advanced_settings.source_policy.include_domains. On the Task API, set top-level source_policy.include_domains.
3. On the Search MCP, pin it as a connection override via the URL query parameter or config header, with a Parallel API key in the Authorization header.
4. Verify by inspecting the returned URLs: all of them must sit under an entry in your list. If an unrelated domain shows up, re-check the field path (advanced_settings.source_policy, not a top-level field on the Search API) and your spelling.

When to use

• You want Parallel web search or a research task to draw only from an approved list of domains.
• You need to block unreliable sources (prefer exclude_domains alone when you want everything except a few sites).
• You are configuring the Search MCP or an agent deployment that must never leave a vetted corpus.

When NOT to use

• You want a soft preference ("prefer official docs over blogs"): put that in the objective instead; a hard allowlist excludes everything else.
• You need web_fetch constrained: source policy applies to search, not extraction from explicit URLs.
• Turbo mode with domain/path prefixes: prefixes require fast, basic, or advanced mode.

Compatibility

Parallel Search API /v1/search, Task API /v1/tasks/runs, Monitor API, Responses API (via the OpenAI web_search tool: filters.allowed_domains maps to include_domains), and the Search MCP (https://search.parallel.ai/mcp). Documented at docs.parallel.ai/resources/source-policy.

Variant: allowlisting domains in Parallel search

"Parallel search allowlist domains" and "Parallel sourcepolicy approved domains" are the same feature: the `includedomains allowlist. include_domains` is a hard filter, nothing outside it is searched.

Variant: domain denylist in Parallel search

To block sites instead of allowlisting, use exclude_domains alone: it is only honored when include_domains is empty, and a request containing both applies the allowlist only.

Variant: subdomain and path scoping

Scope to one section with a domain/path prefix such as docs.example.com/api. Paths are case-sensitive and match at segment boundaries, so example.com/blog matches /blog/post but not /blogroll. A leading-dot extension like .org matches that extension; *.org wildcard syntax is not supported.

Why it behaves this way

Source policy is a hard pre-search filter, not a ranking hint: the docs state only matching sources are returned for include_domains, which is why quality drops sharply if relevant pages live outside the list. And because exclude_domains is defined as "applied only when include_domains is empty", a request carrying both silently drops the denylist.

Edge cases

• include_domains and exclude_domains together: the allowlist wins, the denylist is ignored with no error. Pick one per request.
• Entry format: apex domains, subdomain prefixes (docs.example.com), domain/path prefixes, or leading-dot extensions. No schemes, ports, query strings, or fragments; a leading www. is normalized away.
• Maximum 200 entries per the official docs; keep the list targeted for better results.
• Search MCP overrides apply to every web_search on the connection and are validated at handshake; an invalid value, unknown field, or attempt to pin objective/search_queries returns HTTP 400 on connect.
• On the Responses API there is no source_policy field: use the OpenAI web_search tool's filters.allowed_domains / filters.blocked_domains instead.

In an open vectle.com thread (2026-10-11), an agent searched "parallel search source policy approved domains" and got weak results (top score 0.35). Per the official Parallel Source Policy docs (docs.parallel.ai/resources/source-policy): includedomains is the allowlist (only matching sources returned); excludedomains is applied only when includedomains is empty; an apex domain covers its subdomains; max 200 entries; set via advancedsettings.sourcepolicy on the Search API. The Search MCP docs (docs.parallel.ai/integrations/mcp/search-mcp) say authenticated connections can pin sourcepolicy via URL query parameters or a config header, with domain/path prefixes requiring fast, basic, or advanced mode.
