Note

This tutorial uses LangChain's Python library. For a tutorial that uses the JavaScript library, see Get Started with the LangChain JS/TS Integration.

You can integrate Atlas Vector Search with LangChain to build LLM applications and implement retrieval-augmented generation (RAG). This tutorial demonstrates how to start using Atlas Vector Search with LangChain to perform semantic search on your data and build a RAG implementation. Specifically, you perform the following actions:

Set up the environment.
Store custom data on Atlas.
Create an Atlas Vector Search index on your data.
Run the following vector search queries:
- Semantic search.
- Semantic search with score.
- Semantic search with metadata pre-filtering.
Implement RAG by using Atlas Vector Search to answer questions on your data.

Background

LangChain is an open-source framework that simplifies the creation of LLM applications through the use of "chains." Chains are LangChain-specific components that can be combined for a variety of AI use cases, including RAG.

By integrating Atlas Vector Search with LangChain, you can use Atlas as a vector database and use Atlas Vector Search to implement RAG by retrieving semantically similar documents from your data. To learn more about RAG, see Retrieval-Augmented Generation (RAG) with Atlas Vector Search.

Prerequisites

To complete this tutorial, you must have the following:

An Atlas cluster running MongoDB version 6.0.11, 7.0.2, or later (including RCs).
An OpenAI API Key. You must have a paid OpenAI account with credits available for API requests.
An environment to run interactive Python notebooks such as Colab.
Note
If you're using Colab, ensure that your notebook session's IP address is included in your Atlas project's access list.

Set Up the Environment

Set up the environment for this tutorial. Create an interactive Python notebook by saving a file with the .ipynb extension. This notebook allows you to run Python code snippets individually, and you'll use it to run the code in this tutorial.

To set up your notebook environment:

Install and import dependencies.

Run the following command:

pip install --upgrade --quiet langchain langchain-community langchain-core langchain-mongodb langchain-openai pymongo pypdf

Then, run the following code to import the required packages:

import getpass, os, pymongo, pprint
from langchain_community.document_loaders import PyPDFLoader
from langchain_core.output_parsers import StrOutputParser
from langchain_core.runnables import RunnablePassthrough
from langchain_mongodb import MongoDBAtlasVectorSearch
from langchain_openai import ChatOpenAI, OpenAIEmbeddings
from langchain.prompts import PromptTemplate
from langchain.text_splitter import RecursiveCharacterTextSplitter
from pymongo import MongoClient
from pymongo.operations import SearchIndexModel

Define environmental variables.

Run the following code and provide the following when prompted:

Your OpenAI API Key.
Your Atlas cluster's SRV connection string.

os.environ["OPENAI_API_KEY"] = getpass.getpass("OpenAI API Key:")
ATLAS_CONNECTION_STRING = getpass.getpass("MongoDB Atlas SRV Connection String:")

Note

Your connection string should use the following format:

mongodb+srv://<db_username>:<db_password>@<clusterName>.<hostname>.mongodb.net

Use Atlas as a Vector Store

Then, load custom data into Atlas and instantiate Atlas as a vector database, also called a vector store. Copy and paste the following code snippets into your notebook.

Connect to your Atlas cluster.

Run the following code to establish a connection to your Atlas cluster. It specifies the following:

langchain_db.test as the name of the collection for which to load the data.
vector_index as the name of the Atlas Vector Search index to use for querying the data.

# Connect to your Atlas cluster
client = MongoClient(ATLAS_CONNECTION_STRING)
# Define collection and index name
db_name = "langchain_db"
collection_name = "test"
atlas_collection = client[db_name][collection_name]
vector_search_index = "vector_index"

Load the sample data.

For this tutorial, you use a publicly accessible PDF document titled MongoDB Atlas Best Practices as the data source for your vector store. This document describes various recommendations and core concepts for managing your Atlas deployments.

To load the sample data, run the following code snippet. It does the following:

Retrieves the PDF from the specified URL and loads the raw text data.
Uses a text splitter to split the data into smaller documents.
Specifies chunk parameters, which determines the number of characters in each document and the number of characters that should overlap between two consecutive documents.

# Load the PDF
loader = PyPDFLoader("https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RE4HkJP")
data = loader.load()
# Split PDF into documents
text_splitter = RecursiveCharacterTextSplitter(chunk_size=200, chunk_overlap=20)
docs = text_splitter.split_documents(data)
# Print the first document
docs[0]

Document(page_content='Mong oDB Atlas Best P racticesJanuary 20 19A MongoD B White P aper', metadata={'source': 'https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RE4HkJP', 'page': 0})

Instantiate the vector store.

Run the following code to create a vector store instance named vector_store from the sample documents. This snippet uses the from_documents method to create the MongoDBAtlasVectorSearch vector store and specifies the following parameters:

The sample documents to store in the vector database.
An OpenAI embedding model as the model used to convert text into vector embeddings for the embedding field. By default, this model is text-embedding-ada-002.
langchain_db.test as the Atlas collection to store the documents.
vector_index as the index to use for querying the vector store.

# Create the vector store
vector_store = MongoDBAtlasVectorSearch.from_documents(
    documents = docs,
    embedding = OpenAIEmbeddings(disallowed_special=()),
    collection = atlas_collection,
    index_name = vector_search_index
)

After running the sample code, you can view your vector embeddings in the Atlas UI by navigating to the langchain_db.test collection in your cluster.

Tip

MongoDBAtlasVectorSearch API Reference

Create the Atlas Vector Search Index

Note

To create an Atlas Vector Search index, you must have Project Data Access Admin or higher access to the Atlas project.

To enable vector search queries on your vector store, create an Atlas Vector Search index on the langchain_db.test collection by using the LangChain helper method or the PyMongo driver method.

Run the following code in your notebook your preferred method. The index definition specifies indexing the following fields:

embedding field as the vector type. The embedding field contains the embeddings created using OpenAI's text-embedding-ada-002 embedding model. The index definition specifies 1536 vector dimensions and measures similarity using cosine.
page field as the filter type for pre-filtering data by the page number in the PDF.

# Use helper method to create the vector search index
vector_store.create_vector_search_index(
   dimensions = 1536,
   filters = [ "page" ]
)

Tip

create_vector_search_index API reference

# Create your index model, then create the search index
search_index_model = SearchIndexModel(
   definition={
      "fields": [
         {
         "type": "vector",
         "path": "embedding",
         "numDimensions": 1536,
         "similarity": "cosine"
         },
         {
         "type": "filter",
         "path": "page"
         }
      ]
   },
   name="vector_index",
   type="vectorSearch"
)
atlas_collection.create_search_index(model=search_index_model)

The index should take about one minute to build. While it builds, the index is in an initial sync state. When it finishes building, you can start querying the data in your collection.

Run Vector Search Queries

Once Atlas builds your index, run vector search queries on your data. The following examples demonstrate various queries that you can run on your vectorized data.

The following query uses the similarity_search method to perform a basic semantic search for the string MongoDB Atlas security. It returns a list of documents ranked by relevance.

query = "MongoDB Atlas security"
results = vector_store.similarity_search(query)
pprint.pprint(results)

[Document(page_content='To ensure a secure system right out of the b ox,\nauthentication and I P Address whitelisting are\nautomatically enabled.\nReview the security section of the MongoD B Atlas', metadata={'_id': ObjectId('65c2e8f480f26794dedad8d5'), 'source': 'https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RE4HkJP', 'page': 17}),

The following query uses the similarity_search_with_score method to perform a semantic search for the string MongoDB Atlas security and specifies the k parameter to limit the number of documents to return to 3.

Note

The k parameter in this example refers to the similarity_search_with_score method option, not the knnBeta operator option of the same name.

It returns the three most relevant documents and a relevance score between 0 and 1.

query = "MongoDB Atlas security"
results = vector_store.similarity_search_with_score(
   query = query, k = 3
)
pprint.pprint(results)

You can pre-filter your data by using an MQL match expression that compares the indexed field with boolean, number, or string values. You must index any metadata fields that you want to filter by as the filter type. To learn more, see How to Index Fields for Vector Search.

Note

You specified the page field as a filter when you created the index for this tutorial.

The following query uses the similarity_search_with_score method to perform a semantic search for the string MongoDB Atlas security. It also specifies the following:

The k parameter to limit the number of documents to return to 3.
A pre-filter on the page field that uses the $eq operator to match documents appearing on page 17 only.

It returns the three most relevant documents from page 17 and a relevance score between 0 and 1.

query = "MongoDB Atlas security"
results = vector_store.similarity_search_with_score(
   query = query,
   k = 3,
   pre_filter = { "page": { "$eq": 17 } }
)

Answer Questions on Your Data

This section demonstrates how to implement RAG in your application with Atlas Vector Search and LangChain. Now that you've used Atlas Vector Search to retrieve semantically similar documents, run the following code examples to prompt the LLM to answer questions based on those documents.

This example does the following:

Instantiates Atlas Vector Search as a retriever to query for similar documents, including the optional k parameter to search for only the 10 most relevant documents.

Defines a LangChain prompt template to instruct the LLM to use these documents as context for your query. LangChain passes these documents to the {context} input variable and your query to the {question} variable.
Constructs a chain that specifies the following:
- Atlas Vector Search as the retriever to search for documents to use as context.
- The prompt template that you defined.
- An LLM from OpenAI to generate a context-aware response. By default, this is the gpt-3.5-turbo model.
Prompts the chain with a sample query about Atlas security recommendations.
Returns the LLM's response and the documents used as context. The generated response might vary.

# Instantiate Atlas Vector Search as a retriever
retriever = vector_store.as_retriever(
   search_type = "similarity",
   search_kwargs = { "k": 10 }
)
# Define a prompt template
template = """
   Use the following pieces of context to answer the question at the end.
   {context}
   Question: {question}

prompt = PromptTemplate.from_template(template)
model = ChatOpenAI()
# Construct a chain to answer questions on your data
chain = (
   { "context": retriever, "question": RunnablePassthrough()}
   | prompt
   | model
   | StrOutputParser()
)
# Prompt the chain
question = "How can I secure my MongoDB Atlas cluster?"
answer = chain.invoke(question)
print("Question: " + question)
print("Answer: " + answer)
# Return source documents
documents = retriever.invoke(question)
print("\nSource documents:")
pprint.pprint(documents)

Question: How can I secure my MongoDB Atlas cluster?
Answer: To secure your MongoDB Atlas cluster, you can enable
authentication and IP address whitelisting, review the security section
in the MongoDB Atlas dashboard, encrypt data at rest with encrypted storage
volumes, optionally configure an additional layer of encryption on your
data, set up global clusters on Amazon Web Services, Microsoft Azure,
and Google Cloud Platform, and ensure operational continuity by choosing
appropriate instance size, storage size, and storage speed options.
Additionally, consider setting up a larger number of replica nodes for
increased protection against database downtime.

Question: How can I secure my MongoDB Atlas cluster?
Answer: To secure your MongoDB Atlas cluster, you can enable
authentication and IP Address whitelisting, define permissions
for users and applications, use VPC Peering for secure connectivity,
implement a Defense in Depth approach for securing deployments, and
consider using LDAP integration for centralized authorization
management. It is important to regularly review the security section
of MongoDB Atlas and continuously monitor and update security measures
to mitigate risk and maintain a secure deployment.
