PSINK_S_LARGE_WORD

Phrase sink received an oversized word

PSINK_S_LARGE_WORD is HRESULT 268179 (0x00041793) from Indexing Service. AllStat describes it as “Word larger than maximum length; May be truncated by phrase sink.” 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, PSINK_S_LARGE_WORD means that word larger than maximum length; May be truncated by phrase sink. For PSINK_S_LARGE_WORD, acceptance depends on the returned state and outputs, not only on the cleared severity bit.

Where the status is encountered

• PSINK_S_LARGE_WORD can be returned during legacy Indexing Service catalog processing; log the exact method and object state instead of interpreting the constant outside that contract.
• PSINK_S_LARGE_WORD can be returned during IFilter text and property extraction; log the exact method and object state instead of interpreting the constant outside that contract.
• PSINK_S_LARGE_WORD 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 PSINK_S_LARGE_WORD 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 PSINK_S_LARGE_WORD, preserve phrase sink limit.
• For PSINK_S_LARGE_WORD, preserve incoming token length.
• For PSINK_S_LARGE_WORD, preserve phrase position before and after.
• For PSINK_S_LARGE_WORD, preserve word-sink counterpart.
• For PSINK_S_LARGE_WORD, preserve query behavior for neighboring terms.

Also record psink_s_large_word_operation, psink_s_large_word_state_before, psink_s_large_word_state_after, UTC time, process and thread identifiers, component version, and a correlation ID. When logging PSINK_S_LARGE_WORD, redact secret payloads but preserve stable identifiers and hashes needed for correlation.

What must be true before accepting it

For PSINK_S_LARGE_WORD, verify that phrase construction handles the large token consistently with the word sink and does not corrupt neighboring phrase positions. This check separates a legitimate PSINK_S_LARGE_WORD outcome from code that ignores an incomplete or altered operation.

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

Correct handling and recovery

Apply the sink limit, retain positional continuity, and compare word-sink and phrase-sink output. Disable phrase generation for the token only when the query semantics remain documented.

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

Diagnostic sequence

• Capture the raw value 0x00041793 before wrappers, signed-decimal formatting, exceptions, or generic success handling replace PSINK_S_LARGE_WORD.
• Identify the operation that returned PSINK_S_LARGE_WORD, including interface or callback, component build, thread, process, and the state-machine phase.
• For PSINK_S_LARGE_WORD, prove the decisive condition: phrase construction handles the large token consistently with the word sink and does not corrupt neighboring phrase positions.
• Inspect every output, count, status array, buffer, callback, task state, media timestamp, transaction vote, or security token that remains part of the PSINK_S_LARGE_WORD contract.
• Compare state immediately before and after PSINK_S_LARGE_WORD; success severity does not guarantee that optional work or the caller’s intended high-level action completed.
• Reproduce PSINK_S_LARGE_WORD with the smallest input that retains the same condition, then alter only the recorded cause before repeating the operation.

Difference from nearby results

PSINK_S_LARGE_WORD 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 PSINK_S_LARGE_WORD determines whether the caller stops, waits, consumes output, or changes state.

Developer and administrator guidance

Code should branch on PSINK_S_LARGE_WORD before a generic SUCCEEDED(hr) path whenever outputs, continuation, cancellation, or recovery differ. Telemetry should retain PSINK_S_LARGE_WORD, 0x00041793, the producing method, and a correlation ID.

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

Practical scenario

A long chemical identifier reaches the phrase sink. The host truncates according to the limit, keeps the next token position correct, and verifies phrase searches around the token.

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