Specified by:

add in interface EmbeddingStore<TextSegment>

Parameters:

embedding - The embedding to be added to the store.

textSegment - Original content that was embedded.

Returns:

The auto-generated ID associated with the added embedding.

add

public String add(TextSegment textSegment)

addAll

public List<String> addAll(List<Embedding> embeddings)

Description copied from interface: EmbeddingStore
