FILTER_S_PARTIAL_CONTENTSCAN_IMMEDIATE
Immediate partial content scan is required
FILTER_S_PARTIAL_CONTENTSCAN_IMMEDIATE is HRESULT 268081 (0x00041731) from Indexing Service. The documented description is “A partial content scan of the disk needs to be scheduled for immediate execution.” 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, this result means that a partial content scan of the disk needs to be scheduled for immediate execution. It is actionable success information: the result must be interpreted before the caller advances its workflow.
Where the status is encountered
- Legacy Indexing Service catalog processing; log the exact method and object state instead of interpreting the constant outside that contract.
- IFilter text and property extraction; log the exact method and object state instead of interpreting the constant outside that contract.
- Search enumeration, scan scheduling, or catalog administration; log the exact method and object state instead of interpreting the constant outside that contract.
What must be true before accepting it
Verify that the index manager can identify the affected scope and schedule only the portion whose content state changed. A valid return path and an application-level completed request are not automatically the same thing.
Determine whether ownership, buffers, callbacks, or resources changed before choosing recovery.
Evidence to preserve
- Preserve affected extension or scope.
- Preserve catalog name and generation.
- Preserve reason for invalidation.
- Preserve queued scan identifier.
- Preserve completion and item counts.
Correct handling and recovery
Queue an immediate partial scan with the affected roots or work IDs, coalesce duplicates, and verify that the catalog generation advances after completion.
Difference from nearby results
Practical scenario
A filter update invalidates one file-type subset. The service schedules a partial scan immediately and confirms that unrelated catalog content is not rebuilt.
