Enum Constant Summary

Enum Constants

Enum Constant	Description
GRAPH	Knowledge graph traversal
HIERARCHICAL	Parent-child document retrieval
HYBRID	Combined semantic + keyword, plus knowledge-graph hits when a GraphStore is available.
KEYWORD	BM25/TF-IDF keyword search
MULTI_QUERY	Generate multiple query variations
REASONING	Root-to-leaf tree descent with a model choosing the branch.
SEMANTIC	Vector similarity search
TEMPORAL	Time-weighted retrieval

Method Summary

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

Enum Constant Details

SEMANTIC

public static final Search.Strategy SEMANTIC

Vector similarity search

KEYWORD

public static final Search.Strategy KEYWORD

BM25/TF-IDF keyword search

HYBRID

public static final Search.Strategy HYBRID

Combined semantic + keyword, plus knowledge-graph hits when a GraphStore is available. The three ranked lists fuse through unweighted reciprocal rank fusion. A missing graph store keeps the two-stream fuse; it does not silently become SEMANTIC.

GRAPH

public static final Search.Strategy GRAPH

Knowledge graph traversal

MULTI_QUERY

public static final Search.Strategy MULTI_QUERY

Generate multiple query variations

HIERARCHICAL

public static final Search.Strategy HIERARCHICAL

Parent-child document retrieval

TEMPORAL

public static final Search.Strategy TEMPORAL

Time-weighted retrieval

REASONING

public static final Search.Strategy REASONING

Root-to-leaf tree descent with a model choosing the branch.

Requires a non-blank Search.navigatorModel() served by an installed TreeNavigator. Opposite walk from HIERARCHICAL: this starts at the root and descends.

Method Details

values

public static Search.Strategy[] 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.Strategy 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
