1. Hosting Custom Search Indexes for LLMs on Azure Search


    To host custom search indexes for Large Language Models (LLMs) on Azure Search, we will utilize the Azure Cognitive Search service, which is a fully-managed search-as-a-service in Microsoft's Azure cloud platform. Azure Cognitive Search provides powerful and sophisticated search capabilities on data that you provide, allowing you to build a custom search experience over a wide range of content.

    Here is a step-by-step guide and a Pulumi program in Python that demonstrates how to provision an Azure Cognitive Search service and configure it for use with Large Language Models (LLMs):

    Step 1: Import Required Modules

    First, we need to import the relevant Pulumi Azure Native SDK components that we'll be using to create the Azure Cognitive Search service.

    Step 2: Set Up the Search Service

    We'll instantiate an azure_native.search.Service resource, which represents the Azure Cognitive Search service. Here you'll specify details such as the location, resource group, and SKU that match the requirements of your application.

    Step 3: Configure the Service

    To customize your search service for LLMs, you can set the appropriate properties like partition and replica counts based on your expected load and performance requirements.

    Step 4: Exports and Outputs

    We will export the primary admin key and the URL of the search service, which are needed to interact with the search indexes after the deployment.

    Now, let's see the program that accomplishes the creation of an Azure Cognitive Search service optimized for hosting custom search indexes for LLMs.

    import pulumi import pulumi_azure_native as azure_native # Step 1: Configure the Azure Cognitive Search service. search_service_name = 'llm-search-service' resource_group_name = 'rg-llm-search' # Define the resource group where the search service will be created. resource_group = azure_native.resources.ResourceGroup(resource_group_name) # Define the Azure Cognitive Search service. search_service = azure_native.search.Service(search_service_name, resource_group_name=resource_group.name, location='East US', # You can select the desired Azure location. sku=azure_native.search.SkuArgs(name='Standard_S1'), # Choose the SKU that best fits your needs. # Set other properties for performance, scale, and security as required. ) # Step 2: Obtain the primary admin key of the search service. primary_admin_key = pulumi.Output.all(search_service.name, resource_group.name).apply( lambda args: azure_native.search.list_admin_keys(resource_group_name=args[1], search_service_name=args[0]) ).apply(lambda result: result.primary_key) # Step 3: Export the URL and primary admin key of the search service. pulumi.export('search_service_url', search_service.properties.apply(lambda props: props.public_network_access)) pulumi.export('search_service_primary_admin_key', primary_admin_key)


    • We begin by importing the required Pulumi libraries.
    • We then create an instance of ResourceGroup, which represents the Azure Resource Group that will contain our search service.
    • Next, we create an instance of Service from the azure_native.search namespace, which creates the Azure Cognitive Search service instance within our resource group.
    • The name of the search service (llm-search-service) and its location (East US) are specified, and the SKU is set as Standard_S1. SKUs determine the pricing tier and capabilities; you should choose a SKU that meets your LLMs' performance and pricing requirements.
    • We use the list_admin_keys function to retrieve the primary admin key for the search service. This key is essential for managing the search service, like creating and managing indexes.
    • Lastly, we export the URL and primary admin key. These can be used in the application that will interact with the search service or for further automation.

    With these resources in place, you can proceed to configure your search indexes and load your LLM data for indexing. You would typically create an index schema defining the fields and data types for your data, upload your data, and then implement a search client in your application to query the index.
