Vector store components in Langflow

Vector databases store vector data, which backs AI workloads like chatbots and Retrieval Augmented Generation.

Vector database components establish connections to existing vector databases or create in-memory vector stores for storing and retrieving vector data.

Vector database components are distinct from memory components, which are built specifically for storing and retrieving chat messages from external databases.

Use a vector store component in a flow

This example uses the Astra DB vector store component. Your vector store component's parameters and authentication may be different, but the document ingestion workflow is the same. A document is loaded from a local machine and chunked. The Astra DB vector store generates embeddings with the connected model component, and stores them in the connected Astra DB database.

This vector data can then be retrieved for workloads like Retrieval Augmented Generation.

The user's chat input is embedded and compared to the vectors embedded during document ingestion for a similarity search. The results are output from the vector database component as a Data object and parsed into text. This text fills the {context} variable in the Prompt component, which informs the Open AI model component's responses.

Alternatively, connect the vector database component's Retriever port to a retriever tool, and then to an agent component. This enables the agent to use your vector database as a tool and make decisions based on the available data.

Generate embeddings

The Astra DB Vector Store component offers two methods for generating embeddings.

1. Embedding Model: Use your own embedding model by connecting an Embeddings component in Langflow.

2. Astra Vectorize: Use Astra DB's built-in embedding generation service. When creating a new collection, choose the embeddings provider and models, including NVIDIA's NV-Embed-QA model hosted by Datastax.

important

The embedding model selection is made when creating a new collection and cannot be changed later.

For an example of using the Astra DB Vector Store component with an embedding model, see the Vector Store RAG starter project.

For more information, see the Astra DB Serverless documentation.

Hybrid search

The Astra DB component includes hybrid search, which is enabled by default.

The component fields related to hybrid search are Search Query, Lexical Terms, and Reranker.

• Search Query finds results by vector similarity.
• Lexical Terms is a comma-separated string of keywords, like features, data, attributes, characteristics.
• Reranker is the re-ranker model used in the hybrid search. The re-ranker model is nvidia/llama-3.2-nv.reranker.

Hybrid search performs a vector similarity search and a lexical search, compares the results of both searches, and then returns the most relevant results overall.

important

To use hybrid search, your collection must be created with vector, lexical, and rerank capabilities enabled. These capabilities are enabled by default when you create a collection in a database in the AWS us-east-2 region. For more information, see the DataStax documentation.

To use Hybrid search in the Astra DB component, do the following:

1. Click New Flow > RAG > Hybrid Search RAG.
2. In the OpenAI model component, add your OpenAI API key.
3. In the Astra DB vector store component, add your Astra DB Application Token.
4. In the Database field, select your database.
5. In the Collection field, select or create a collection with hybrid search capabilities enabled.
6. In the Playground, enter a question about your data, such as What are the features of my data? Your query is sent to two components: an OpenAI model component and the Astra DB vector database component. The OpenAI component contains a prompt for creating the lexical query from your input:

_10

You are a database query planner that takes a user's requests, and then converts to a search against the subject matter in question.

_10

You should convert the query into:

_10

1. A list of keywords to use against a Lucene text analyzer index, no more than 4. Strictly unigrams.

_10

2. A question to use as the basis for a QA embedding engine.

_10

Avoid common keywords associated with the user's subject matter.

7. To view the keywords and questions the OpenAI component generates from your collection, in the OpenAI component, click .

_10

1. Keywords: features, data, attributes, characteristics

_10

2. Question: What characteristics can be identified in my data?

8. To view the DataFrame generated from the OpenAI component's response, in the Structured Output component, click . The DataFrame is passed to a Parser component, which parses the contents of the Keywords column into a string.

   This string of comma-separated words is passed to the Lexical Terms port of the Astra DB component. Note that the Search Query port of the Astra DB port is connected to the Chat Input component from step 6. This Search Query is vectorized, and both the Search Query and Lexical Terms content are sent to the reranker at the find_and_rerank endpoint.

   The reranker compares the vector search results against the string of terms from the lexical search. The highest-ranked results of your hybrid search are returned to the Playground.

For more information, see the DataStax documentation.

This example splits text from a URL component, and computes embeddings with the connected OpenAI Embeddings component. Chroma DB computes embeddings by default, but you can connect your own embeddings model, as seen in this example.

3. Optionally, to persist the Chroma database, in the Persist field, enter a directory to store the chroma.sqlite3 file. This example uses ./chroma-db to create a directory relative to where Langflow is running.
4. To load data and embeddings into your Chroma database, in the Chroma DB component, click .

tip

When loading duplicate documents, enable the Allow Duplicates option in Chroma DB if you want to store multiple copies of the same content, or disable it to automatically deduplicate your data.

5. To view the split data, in the Split Text component, click .
6. To query your loaded data, open the Playground and query your database. Your input is converted to vector data and compared to the stored vectors in a vector similarity search.
