Use for the vast majority of public-web research tasks, from precise lookups to difficult investigations. This general-purpose multi-engine search does not require Jev. If adaptive_search is unavailable, disabled or Jev is not configured, use enabled fused_search normally; do not delay research or require Jev setup. When both tools are available, choose fused_search for direct retrieval, varied query angles or explicit source control. Prefer adaptive_search for higher-quality intent-guided evidence selection when a medium-to-high difficulty or uncertain question benefits from screening noisy or mixed-relevance results. Choose by the evidence need, not merely by which tools are configured. Returns ranked extracts, source attribution and execution diagnostics, including failures and warnings. Normally omit engines; request-local choices do not change persistent defaults. Add X community voices when relevant; use x_search for X-only tasks. Scores do not verify claims, and multiple engines finding the same page do not independently corroborate it. Use fetch_page to read decisive sources when extracts are insufficient. Optional live status: search-boost://capabilities Resource.

Read a known HTTP(S) URL without searching again. Returns readable HTML or locally extracted PDF text, with retrieval route and any extraction limitations. Long bodies use bounded windows; continue from nextOffset using the cached read, not a new request. A focus miss is not evidence of absence: retry without focus. Binary bodies and PDFs with no extractable text return errors, not page text. Network safety, proxy policy, cancellation and size limits remain enforced through all supported fallbacks. This is not an authenticated browser.

Find X/Twitter posts, account material or available thread content. Credential-free retrieval is supported; configured authentication can improve coverage. Results include source attribution and diagnostics. Author/date filters require verifiable metadata; unverified candidates are omitted. Coverage may be incomplete, stale or empty. A post sample does not establish platform-wide sentiment, and a thread result need not contain the full conversation.

Inspect the current search layer with layer=show (default, no change). layer=free or api persists a new default: only change it when authorized. free = free — compatibility default engine_pool=free (keyless). api = api — compatibility default engine_pool=hybrid (keyless plus configured APIs). For a single search, use fused_search.engine_pool instead; legacy api maps to hybrid, not the strict api pool.

Read-only search diagnostics: cache activity, engine configuration readiness and recent searches. Inspect result warnings as well; empty results do not prove absence or authorize changing credentials, permissions or defaults.
