CI_E_NOT_FOUND

The requested content-index object was not found

CI_E_NOT_FOUND is HRESULT 0x80041815 (-2147215339 signed; 2147751957 unsigned). Its severity bit is 1, facility is 4 (FACILITY_ITF for these values), and code field is 0x1815. For CI_E_NOT_FOUND, standard HRESULT severity rules classify the value as a failure. AllStat describes the value as “The object was not found.”

Where the result belongs

CI_E_NOT_FOUND belongs to looking up a catalog item, helper object or indexed entity by the supplied identity. The decisive interpretation is that no matching object exists in the target scope at lookup time. For CI_E_NOT_FOUND, keep the symbolic constant and method stage together in logs; its hexadecimal value alone cannot identify the owning transition or input.

For CI_E_NOT_FOUND, the legacy content-index helper layer has explicit object, catalog and service states. In the CI_E_NOT_FOUND investigation, a generic retry can hide lifecycle, ordering or policy defects. This context narrows the responsible component without replacing the code-specific checks below.

Concrete causes

  • For CI_E_NOT_FOUND, check the item was removed.
  • For CI_E_NOT_FOUND, check the caller selected the wrong catalog or scope.
  • For CI_E_NOT_FOUND, check indexing has not created the object yet.
  • For CI_E_NOT_FOUND, check identity normalization differs from the stored form.

The useful hypothesis for CI_E_NOT_FOUND must explain both looking up a catalog item, helper object or indexed entity by the supplied identity and the documented condition. Compare the failing case with a control that preserves object type and canonical identity and changes only catalog and scope; this prevents unrelated environment differences from dominating the CI_E_NOT_FOUND test.

Evidence to retain

  • Object type and canonical identity; preserve the observation under the CI_E_NOT_FOUND correlation record.
  • Catalog and scope; preserve the observation under the CI_E_NOT_FOUND correlation record.
  • Lookup timestamp versus ingestion events; preserve the observation under the CI_E_NOT_FOUND correlation record.
  • Normalization performed by the caller; preserve the observation under the CI_E_NOT_FOUND correlation record.

For CI_E_NOT_FOUND, capture object type and canonical identity before releasing objects, closing handles or reconnecting. Retain the raw HRESULT with catalog and scope, component version, UTC timestamp and correlation ID. Bound the CI_E_NOT_FOUND telemetry to diagnostic metadata because document content, credentials and unrestricted query text may be sensitive.

Diagnostic path

  1. Repeat the lookup only after verifying the target scope. Associate this observation specifically with CI_E_NOT_FOUND.
  2. Correlate creation/deletion events. Associate this observation specifically with CI_E_NOT_FOUND.
  3. Compare canonical identifiers, not display labels. Associate this observation specifically with CI_E_NOT_FOUND.
  4. Distinguish expected absence from ingestion lag. Associate this observation specifically with CI_E_NOT_FOUND.

Change one variable per CI_E_NOT_FOUND control run. Preserve the component version and target identity, then alter only the condition described as no matching object exists in the target scope at lookup time. This isolates whether CI_E_NOT_FOUND is causal rather than merely repeatable.

Recovery and retry

Create, ingest or correctly identify the object before retrying. Absence may be a valid application outcome. For CI_E_NOT_FOUND, record whether looking up a catalog item, helper object or indexed entity by the supplied identity produced any content, update or state transition before returning. If completion remains unknown, the CI_E_NOT_FOUND path must not replay non-idempotent work until the owner confirms final state.

The retry gate for CI_E_NOT_FOUND should be a concrete change in object type and canonical identity or catalog and scope. A timer alone cannot demonstrate that the CI_E_NOT_FOUND contract condition has changed.

What must not be inferred

It does not by itself prove an invalid work ID or a missing catalog. Without the call boundary for looking up a catalog item, helper object or indexed entity by the supplied identity, CI_E_NOT_FOUND also cannot identify which wrapper or configuration layer introduced the condition.

Nearby results

CI_E_WORKID_NOTVALID rejects a work-ID representation; CI_E_NO_CATALOG says the containing catalog is absent. In CI_E_NOT_FOUND telemetry, preserve neighboring constants separately because the same visible symptom may require a different caller action, owner or recovery gate.

Developer and administrator actions

  • The CI_E_NOT_FOUND investigation should record At the code boundary, keep object type and canonical identity beside the returned HRESULT.
  • The CI_E_NOT_FOUND investigation should record In telemetry, correlate catalog and scope with the target and component generation.
  • The CI_E_NOT_FOUND investigation should record For regression coverage, force the documented condition: no matching object exists in the target scope at lookup time.
  • The CI_E_NOT_FOUND investigation should record For operations staff, expose the corrective state change rather than a generic retry button.
  • The CI_E_NOT_FOUND investigation should record After remediation, validate one known-good control and the original failing case.

Operational example

An update request uses a path normalized differently from the indexed URL. Canonical identity logging reveals why lookup returns no object. In this scenario, handling CI_E_NOT_FOUND at its real contract boundary prevents the application from collapsing a precise state into an unhelpful generic “search failed” message.
