Enum FilterPredicate 

pub enum FilterPredicate {
    MinScore(DeterministicScore),
    TopK(usize),
    MetadataEquals {
        field: String,
        value: Value,
    },
    And(Vec<FilterPredicate>),
    Or(Vec<FilterPredicate>),
}

Predicate for post-retrieval filtering.

Variants

MinScore(DeterministicScore)

Keep only results whose score meets a minimum threshold.

TopK(usize)

Keep at most k results (top-k truncation).

MetadataEquals

Keep results where a metadata field equals a given value.

Fields

field: String

Metadata field name.

value: Value

Expected value (JSON).

And(Vec<FilterPredicate>)

All contained predicates must hold (conjunction).

Or(Vec<FilterPredicate>)

At least one contained predicate must hold (disjunction).
