Struct EmbeddingStore 

pub struct EmbeddingStore { /* private fields */ }

SQLite embedding store with FTS5 hybrid search

Implementations

impl EmbeddingStore

pub fn new_in_memory() -> SqlResult<Self>

Create a new embedding store (in-memory for testing)

pub fn open(path: &Path) -> SqlResult<Self>

Open or create an embedding store from file

pub fn insert_chunk( &mut self, chunk: &Chunk, embedding: &[f32], ) -> SqlResult<()>

Insert a chunk with its embedding

pub fn get_chunk(&self, id: &str) -> SqlResult<Option<Chunk>>

Get a chunk by ID

pub fn get_embedding(&self, chunk_id: &str) -> SqlResult<Option<Vec<f32>>>

Get embedding for a chunk

pub fn search_keywords( &self, query: &str, limit: usize, ) -> SqlResult<Vec<ChunkMatch>>

FTS5 keyword search

pub fn search_similar( &self, query_embedding: &[f32], limit: usize, ) -> SqlResult<Vec<ChunkMatch>>

Vector similarity search (brute force for now, fast enough for <100K chunks)

pub fn hybrid_search( &self, keywords: &str, query_embedding: &[f32], limit: usize, ) -> SqlResult<Vec<ChunkMatch>>

Hybrid search: Combine FTS5 + vector similarity

pub fn get_children(&self, parent_id: &str) -> SqlResult<Vec<Chunk>>

Get all child chunks of a parent

pub fn count_chunks(&self) -> SqlResult<usize>

Count total chunks
