Struct HybridIndex 

pub struct HybridIndex { /* private fields */ }

Hybrid search index combining vector and keyword search

Implementations

impl HybridIndex

pub fn new(config: HybridConfig) -> Self

Create a new hybrid search index

pub fn build( &mut self, embeddings: &HashMap<String, Vec<f32>>, texts: &HashMap<String, String>, ) -> Result<()>

Build hybrid index from embeddings and texts

pub fn search( &self, query_vector: &[f32], query_text: &str, k: usize, ) -> Result<Vec<HybridSearchResult>>

Hybrid search combining vector and keyword results

Uses Reciprocal Rank Fusion (RRF) to combine results.

pub fn weighted_search( &self, query_vector: &[f32], query_text: &str, k: usize, ) -> Result<Vec<HybridSearchResult>>

Search using weighted linear combination instead of RRF

pub fn vector_search( &self, query: &[f32], k: usize, ) -> Result<Vec<SearchResult>>

Vector-only search (alpha = 1.0)

pub fn keyword_search( &self, query: &str, k: usize, ) -> Result<Vec<HybridSearchResult>>

Keyword-only search (alpha = 0.0)

pub fn get_stats(&self) -> HybridStats

Get index statistics

pub fn set_alpha(&mut self, alpha: f32)

Set alpha parameter (vector vs keyword weight)
