What does HRESULT 0x000416A0 (SEARCH_S_NOMOREHITS) mean?

SEARCH_S_NOMOREHITS

Search enumeration reached the end of hits

SEARCH_S_NOMOREHITS is HRESULT 267936 (0x000416A0) from Indexing Service. AllStat describes it as “End of hits has been reached.” The severity bit indicates a nonfailure result, but the value carries a specific condition that must not be collapsed into plain S_OK.

In the legacy Indexing Service or IFilter pipeline, SEARCH_S_NOMOREHITS means that end of hits has been reached. Before reporting completion for SEARCH_S_NOMOREHITS, the caller must reconcile the code-specific state transition and every usable output.

Where the status is encountered

• SEARCH_S_NOMOREHITS can be returned during legacy Indexing Service catalog processing; log the exact method and object state instead of interpreting the constant outside that contract.
• SEARCH_S_NOMOREHITS can be returned during IFilter text and property extraction; log the exact method and object state instead of interpreting the constant outside that contract.
• SEARCH_S_NOMOREHITS can be returned during search enumeration, scan scheduling, or catalog administration; log the exact method and object state instead of interpreting the constant outside that contract.

Because SEARCH_S_NOMOREHITS is informational, a language binding may expose it as success and hide the symbolic distinction. Keep the original HRESULT available until the code-specific branch has run.

Evidence and telemetry

• For SEARCH_S_NOMOREHITS, preserve query text and scope.
• For SEARCH_S_NOMOREHITS, preserve catalog generation.
• For SEARCH_S_NOMOREHITS, preserve page size and cumulative hit count.
• For SEARCH_S_NOMOREHITS, preserve last work ID or bookmark.
• For SEARCH_S_NOMOREHITS, preserve enumerator lifetime.

Also record search_s_nomorehits_operation, search_s_nomorehits_state_before, search_s_nomorehits_state_after, UTC time, process and thread identifiers, component version, and a correlation ID. Telemetry for SEARCH_S_NOMOREHITS should omit credentials while retaining nonsecret object identities and version data.

What must be true before accepting it

For SEARCH_S_NOMOREHITS, verify that the consumer has processed every returned hit and stops without treating normal exhaustion as an error. Without that proof, SEARCH_S_NOMOREHITS can mask a caller error even though HRESULT failure severity is not set.

Reconcile side effects associated with SEARCH_S_NOMOREHITS before compensation or a second invocation is attempted.

Correct handling and recovery

Finish the enumeration, release query handles, and retain the final count. Retry only after the catalog or query changes, not to obtain more rows from the same exhausted cursor.

Retry SEARCH_S_NOMOREHITS only when a documented input or state has changed. An unchanged retry after SEARCH_S_NOMOREHITS is useful only when the API explicitly advances through repeated calls.

Diagnostic sequence

• Capture the raw value 0x000416A0 before wrappers, signed-decimal formatting, exceptions, or generic success handling replace SEARCH_S_NOMOREHITS.
• Identify the operation that returned SEARCH_S_NOMOREHITS, including interface or callback, component build, thread, process, and the state-machine phase.
• For SEARCH_S_NOMOREHITS, prove the decisive condition: the consumer has processed every returned hit and stops without treating normal exhaustion as an error.
• Inspect every output, count, status array, buffer, callback, task state, media timestamp, transaction vote, or security token that remains part of the SEARCH_S_NOMOREHITS contract.
• Compare state immediately before and after SEARCH_S_NOMOREHITS; success severity does not guarantee that optional work or the caller’s intended high-level action completed.
• Reproduce SEARCH_S_NOMOREHITS with the smallest input that retains the same condition, then alter only the recorded cause before repeating the operation.

Difference from nearby results

SEARCH_S_NOMOREHITS must be distinguished from ordinary S_OK and from failure-severity values in the same API family; its documented state changes control the next action.

Correctly separating SEARCH_S_NOMOREHITS from neighboring values selects the proper continuation and cleanup path.

Developer and administrator guidance

Operational dashboards should classify SEARCH_S_NOMOREHITS as its actual state—pending, terminal, partial, cancelled, adapted, or warning-like success—rather than counting it as either an ordinary failure or undifferentiated success.

For SEARCH_S_NOMOREHITS, document ownership of retry, cancellation, cleanup, and user messaging. For SEARCH_S_NOMOREHITS, change the owning configuration or state only after the captured evidence identifies it as causal.

Practical scenario

A search client reads pages of results until this status arrives. It shows the exact total and closes the command instead of displaying a failure banner.

A regression test should reproduce SEARCH_S_NOMOREHITS, assert the relevant outputs and state, then change only the decisive condition and verify the expected neighboring result or ordinary completion.
