Detailed Description¶

RAG retrieval node. Embeds the HumanMessage, searches an embedded storage, and attaches a KnowledgeComponent to the current interaction.

Public Attributes Documentation¶

variable EmbeddedStringStorage¶

FTryllStoragePath UTryllRetrieveParams::EmbeddedStringStorage;

Named embedded string storage (EmbeddedStringStorageManager). Structural because the storage is resolved and referenced at construction.

variable Filter¶

FString UTryllRetrieveParams::Filter;

variable FoundExit¶

FString UTryllRetrieveParams::FoundExit;

Exit taken when retrieval returned at least one chunk above threshold. Empty string = END. Graph exit "found" — target node name; empty = END.

variable Input¶

FTryllSlotInput UTryllRetrieveParams::Input;

Upstream inter-node slot this field consumes. Empty = context default.

variable NotFoundExit¶

FString UTryllRetrieveParams::NotFoundExit;

Exit taken when retrieval produced no results. Empty string = END. Graph exit "not_found" — target node name; empty = END.

variable RetrievalMode¶

ETryllRetrievalMode UTryllRetrieveParams::RetrievalMode;

Which retrieval path to use. Default Dense preserves historical behaviour. Mutable so a single agent can A/B modes without recreation.

variable RrfK¶

int32 UTryllRetrieveParams::RrfK;

RRF constant k in score(d) = Σ 1/(k + rank). Only used in Hybrid mode. Mutable. Default 60 (Cormack et al.).

variable Source¶

FString UTryllRetrieveParams::Source;

variable Threshold¶

float UTryllRetrieveParams::Threshold;

Maximum cosine distance applied to the dense leg. Dense mode: results above this threshold are dropped (unchanged historical behaviour). Hybrid mode: gates the dense candidate list before RRF fusion; BM25-only hits are not gated. Lexical mode: inert (ignored). Zero disables dense-leg filtering.

variable TopK¶

int32 UTryllRetrieveParams::TopK;

Number of chunks to retrieve.

variable bOverrideFilter¶

bool UTryllRetrieveParams::bOverrideFilter;

JSON filter compiled against the storage's metadata schema. Empty string = no filter. Mutable — recompiles the filter on change. Set to true to override the inherited Filter value.

variable bOverrideInput¶

bool UTryllRetrieveParams::bOverrideInput;

Slot name this node embeds and searches with. Empty = "user_message". Structural: immutable after creation — rebinding would re-wire the slot dataflow that is validated once at agent creation. Set to true to override the inherited Input value.

variable bOverrideSource¶

bool UTryllRetrieveParams::bOverrideSource;

Label attached to the KnowledgeComponent; defaults to node name. Set to true to override the inherited Source value.

Public Functions Documentation¶

function GetNodeType¶

inline virtual ETryllNodeType UTryllRetrieveParams::GetNodeType () override const

Implements UTryllNodeParamsBase::GetNodeType

function Pack¶

virtual flatbuffers::Offset< void > UTryllRetrieveParams::Pack (
    flatbuffers::FlatBufferBuilder & Fbb,
    Tryll::NodeParams::NodeParams & OutType
) override const

Implements UTryllNodeParamsBase::Pack
