Struct TextQueryBuilder 

pub struct TextQueryBuilder { /* private fields */ }

Builder for TextQuery, ranking points by BM25 over the text index of a payload field.

The payload field is selected with using on the query request, and its text index must have scoring enabled, see TextIndexParamsBuilder::bm25_scoring.

Implementations

impl TextQueryBuilder

pub fn new(query: impl Into<String>) -> Self

Create a new TextQueryBuilder for the given text.

Examples

use qdrant_client::qdrant::TextQueryBuilder;

let text_query = TextQueryBuilder::new("vector database").k(1.5).b(0.5).build();

pub fn k(self, value: f32) -> Self

Term frequency saturation. Default is 1.2.

pub fn b(self, value: f32) -> Self

Document length normalization, from 0 (none) to 1 (full). Default is 0.75.

pub fn build(self) -> TextQuery

Builds the query. k and b go in the BM25 scorer’s parameters; with neither set, the scorer runs with its defaults.
