Ranking function for unified query API Supports vector search (ANN/kNN), full-text BM25, and attribute ordering

Variants

VectorSearch

Vector search: [“vector_field”, “ANN”|“kNN”, [query_vector]] or simplified: [“ANN”, [query_vector]] for default “vector” field

Fields

field: String

method: VectorSearchMethod

query_vector: Vec<f32>

FullTextSearch

Full-text BM25 search: [“text_field”, “BM25”, “query string”]

Fields

field: String

method: String

query: String

AttributeOrder

Attribute ordering: [“field_name”, “asc”|“desc”]

Fields

field: String

direction: SortDirection

Sum(Vec<RankBy>)

Sum of multiple ranking functions: [“Sum”, […rankings]]

Max(Vec<RankBy>)

Max of multiple ranking functions: [“Max”, […rankings]]

Product

Product with weight: [“Product”, weight, ranking]

Fields

weight: f32

ranking: Box<RankBy>
