Struct SparseQueryConfig 

pub struct SparseQueryConfig {
    pub tokenizer: Option<String>,
    pub weighting: QueryWeighting,
    pub heap_factor: f32,
    pub max_query_dims: Option<usize>,
}

Query-time configuration for sparse vectors

Fields

tokenizer: Option<String>

HuggingFace tokenizer path/name for query-time tokenization Example: “Alibaba-NLP/gte-Qwen2-1.5B-instruct”

weighting: QueryWeighting

Weighting strategy for tokenized query terms

heap_factor: f32

Heap factor for approximate search (SEISMIC-style optimization) A block is skipped if its max possible score < heap_factor * threshold

• 1.0 = exact search (default)
• 0.8 = approximate, ~20% faster with minor recall loss
• 0.5 = very approximate, much faster

max_query_dims: Option<usize>

Maximum number of query dimensions to process (query pruning) Processes only the top-k dimensions by weight

• None = process all dimensions (default)
• Some(10) = process top 10 dimensions only

Trait Implementations

impl Clone for SparseQueryConfig

fn clone(&self) -> SparseQueryConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SparseQueryConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SparseQueryConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SparseQueryConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SparseQueryConfig

fn eq(&self, other: &SparseQueryConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SparseQueryConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
