Delete Data

Chroma supports deleting items from a collection by id using .delete. The embeddings, documents, and metadata associated with each item will be deleted.

collection.delete(
    ids=["id1", "id2", "id3",...],
)

await collection.delete({
    ids: ["id1", "id2", "id3",...],
})

collection.delete(
    Some(vec!["id1".to_string(), "id2".to_string(), "id3".to_string()]),
    None,
).await?;

.delete also supports the where filter. It will delete all items in the collection that match the where filter.

collection.delete(
	where={"chapter": "20"}
)

await collection.delete({
    where: {"chapter": "20"} //where
})

use chroma::types::{MetadataComparison, MetadataExpression, MetadataValue, PrimitiveOperator, Where};

let where_clause = Where::Metadata(MetadataExpression {
    key: "chapter".to_string(),
    comparison: MetadataComparison::Primitive(
        PrimitiveOperator::Equal,
        MetadataValue::Str("20".to_string()),
    ),
});

collection.delete(
    None,
    Some(where_clause),
).await?;
