What does HRESULT 0x00041709 (FILTER_S_LAST_TEXT) mean?

FILTER_S_LAST_TEXT

Filter returned the final text for the current chunk

FILTER_S_LAST_TEXT is HRESULT 268041 (0x00041709) from Indexing Service. AllStat describes it as “This is the last text in the current chunk.” 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, FILTER_S_LAST_TEXT means that this is the last text in the current chunk. For FILTER_S_LAST_TEXT, acceptance depends on the returned state and outputs, not only on the cleared severity bit.

Diagnostic sequence

• Capture the raw value 0x00041709 before wrappers, signed-decimal formatting, exceptions, or generic success handling replace FILTER_S_LAST_TEXT.
• Identify the operation that returned FILTER_S_LAST_TEXT, including interface or callback, component build, thread, process, and the state-machine phase.
• For FILTER_S_LAST_TEXT, prove the decisive condition: the text buffer is consumed once and no additional GetText call is assumed to yield data for this chunk.
• Inspect every output, count, status array, buffer, callback, task state, media timestamp, transaction vote, or security token that remains part of the FILTER_S_LAST_TEXT contract.
• Compare state immediately before and after FILTER_S_LAST_TEXT; success severity does not guarantee that optional work or the caller’s intended high-level action completed.
• Reproduce FILTER_S_LAST_TEXT with the smallest input that retains the same condition, then alter only the recorded cause before repeating the operation.

Where the status is encountered

• FILTER_S_LAST_TEXT can be returned during legacy Indexing Service catalog processing; log the exact method and object state instead of interpreting the constant outside that contract.
• FILTER_S_LAST_TEXT can be returned during IFilter text and property extraction; log the exact method and object state instead of interpreting the constant outside that contract.
• FILTER_S_LAST_TEXT 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 FILTER_S_LAST_TEXT 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.

What must be true before accepting it

For FILTER_S_LAST_TEXT, verify that the text buffer is consumed once and no additional GetText call is assumed to yield data for this chunk. This check separates a legitimate FILTER_S_LAST_TEXT outcome from code that ignores an incomplete or altered operation.

Before retrying FILTER_S_LAST_TEXT, classify its effects as completed, partial, pending, cancelled, adapted, or terminal.

Evidence and telemetry

• For FILTER_S_LAST_TEXT, preserve chunk ID and break type.
• For FILTER_S_LAST_TEXT, preserve characters requested and returned.
• For FILTER_S_LAST_TEXT, preserve source and destination offsets.
• For FILTER_S_LAST_TEXT, preserve text buffer encoding.
• For FILTER_S_LAST_TEXT, preserve next GetChunk result.

Also record filter_s_last_text_operation, filter_s_last_text_state_before, filter_s_last_text_state_after, UTC time, process and thread identifiers, component version, and a correlation ID. When logging FILTER_S_LAST_TEXT, redact secret payloads but preserve stable identifiers and hashes needed for correlation.

Difference from nearby results

FILTER_S_LAST_TEXT 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.

The distinction around FILTER_S_LAST_TEXT determines whether the caller stops, waits, consumes output, or changes state.

Correct handling and recovery

Index the returned characters, preserve their source offsets, and move to the next chunk. Do not discard the final buffer merely because the status is not plain S_OK.

Retry FILTER_S_LAST_TEXT only when a documented input or state has changed. Do not immediately repeat FILTER_S_LAST_TEXT when the same stable state would produce the same informational result.

Practical scenario

An IFilter implementation returns 120 characters together with this status. The host indexes those characters and then calls GetChunk, avoiding loss of the final sentence.

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

Developer and administrator guidance

Code should branch on FILTER_S_LAST_TEXT before a generic SUCCEEDED(hr) path whenever outputs, continuation, cancellation, or recovery differ. Telemetry should retain FILTER_S_LAST_TEXT, 0x00041709, the producing method, and a correlation ID.

For FILTER_S_LAST_TEXT, document ownership of retry, cancellation, cleanup, and user messaging. Administration for FILTER_S_LAST_TEXT should target the component that returned it instead of applying broad restarts.
