Method Details

builder

public static MilvusV2EmbeddingStore.Builder builder()

dropCollection

public void dropCollection(String collectionName)

add

public String add(Embedding embedding)

Description copied from interface: EmbeddingStore

Adds a given embedding to the store.

Specified by:

add in interface EmbeddingStore<TextSegment>

Parameters:

embedding - The embedding to be added to the store.

Returns:

The auto-generated ID associated with the added embedding.

add

public void add(String id,
 Embedding embedding)

Description copied from interface: EmbeddingStore

Adds a given embedding to the store.

Specified by:

add in interface EmbeddingStore<TextSegment>

Parameters:

id - The unique identifier for the embedding to be added.

embedding - The embedding to be added to the store.

add

public String add(Embedding embedding,
 TextSegment textSegment)

Description copied from interface: EmbeddingStore

Adds a given embedding and the corresponding content that has been embedded to the store.

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.

addAll

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

Description copied from interface: EmbeddingStore

Adds multiple embeddings to the store.

Specified by:

addAll in interface EmbeddingStore<TextSegment>

Parameters:

embeddings - A list of embeddings to be added to the store.

Returns:

A list of auto-generated IDs associated with the added embeddings.

search

public EmbeddingSearchResult<TextSegment> search(EmbeddingSearchRequest request)

Description copied from interface: EmbeddingStore

Searches for the most similar (closest in the embedding space) Embeddings.
All search criteria are defined inside the EmbeddingSearchRequest.
EmbeddingSearchRequest.filter() can be used to filter by various metadata entries (e.g., user/memory ID). Please note that not all EmbeddingStore implementations support Filtering.

Specified by:

search in interface EmbeddingStore<TextSegment>

Parameters:

request - A request to search in an EmbeddingStore. Contains all search criteria.

Returns:

An EmbeddingSearchResult containing all found Embeddings.

search

public EmbeddingSearchResult<TextSegment> search(MilvusV2EmbeddingSearchRequest embeddingSearchRequest)

addAll

public void addAll(List<String> ids,
 List<Embedding> embeddings,
 List<TextSegment> textSegments)

Description copied from interface: EmbeddingStore

Adds multiple embeddings and their corresponding contents that have been embedded to the store.

Specified by:

addAll in interface EmbeddingStore<TextSegment>

Parameters:

ids - A list of IDs associated with the added embeddings.

embeddings - A list of embeddings to be added to the store.

textSegments - A list of original contents that were embedded.

addAllSparse

public void addAllSparse(List<String> ids,
 List<SparseEmbedding> embeddings,
 List<TextSegment> textSegments)

addAllHybrid

public void addAllHybrid(List<String> ids,
 List<Embedding> denseEmbeddings,
 List<SparseEmbedding> sparseEmbeddings,
 List<TextSegment> textSegments)

removeAll

public void removeAll(Collection<String> ids)

Removes a single embedding from the store by ID.

CAUTION

• Deleted entities can still be retrieved immediately after the deletion if the consistency level is set lower than Strong
• Entities deleted beyond the pre-specified span of time for Time Travel cannot be retrieved again.
• Frequent deletion operations will impact the system performance.
• Before deleting entities by comlpex boolean expressions, make sure the collection has been loaded.
• Deleting entities by complex boolean expressions is not an atomic operation. Therefore, if it fails halfway through, some data may still be deleted.
• Deleting entities by complex boolean expressions is supported only when the consistency is set to Bounded. For details, see Consistency

Specified by:

removeAll in interface EmbeddingStore<TextSegment>

Parameters:

ids - A collection of unique IDs of the embeddings to be removed.

Since:

Milvus version 2.3.x

removeAll

public void removeAll(Filter filter)

Removes all embeddings that match the specified Filter from the store.

CAUTION

• Deleting entities by complex boolean expressions is supported only when the consistency is set to Bounded. For details, see Consistency

Specified by:

removeAll in interface EmbeddingStore<TextSegment>

Parameters:

filter - The filter to be applied to the Metadata of the TextSegment during removal. Only embeddings whose TextSegment's Metadata match the Filter will be removed.

Since:

Milvus version 2.3.x

removeAll

public void removeAll()

Removes all embeddings from the store.
