Enum Constant Summary

Enum Constants

Enum Constant	Description
CONTINUE	Continue without context
FAIL	Throw exception
RETRY_SIMPLE	Retry once with a punctuation-normalized query against Search.Strategy.KEYWORD, without reranking.
USE_CACHE	Fall back to the expired cached result for the identical retrieval, rethrowing the failure when there is none.

Method Summary

Modifier and Type	Method	Description
static Search.FallbackAction	valueOf(String name)	Returns the enum constant of this class with the specified name.
static Search.FallbackAction[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

CONTINUE

public static final Search.FallbackAction CONTINUE

Continue without context

FAIL

public static final Search.FallbackAction FAIL

Throw exception

USE_CACHE

public static final Search.FallbackAction USE_CACHE

Fall back to the expired cached result for the identical retrieval, rethrowing the failure when there is none. Requires Search.cache(), and only serves an entry still within Search.maxStaleness() of its expiry — past that the original failure is rethrown, so a prolonged outage cannot keep answering from ever-older grounding.

RETRY_SIMPLE

public static final Search.FallbackAction RETRY_SIMPLE

Retry once with a punctuation-normalized query against Search.Strategy.KEYWORD, without reranking.

When Search.rerank() is enabled the retry is still capped at Search.topN() even though no reranker runs, so losing the reranker cannot widen the injected context beyond what the healthy path would have delivered. With Search.rerank() disabled Search.topN() is unvalidated and applies to no path, primary or fallback, so the retry is bounded only by Search.topK().

Method Details

values

public static Search.FallbackAction[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Search.FallbackAction valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
