Hi @Balaji Mogadali ,
Welcome to the Microsoft Q&A Platform!
To check document-level access for a user in SharePoint using AI Search while leveraging the existing identity of a user, you need to combine SharePoint API capabilities with AI Search.

Set Up Azure Cognitive Search Index SharePoint documents into Azure Cognitive Search.

Ensure document metadata includes user/group permissions.

Use Azure Data Factory or APIs for indexing SharePoint content.

Use Microsoft Graph API to retrieve the user's identity and permissions. GET https://graph.microsoft.com/v1.0/me

Ensure proper Azure AD Authentication.

Use Azure Cognitive Search SDK in C# to filter results based on the user's identity. Filter = $"permissions/any(p: p eq '{userPrincipalName}')"

Use SharePoint REST API or Microsoft Graph API to confirm user permissions for a specific document. GET /sites/{site-id}/drives/{drive-id}/items/{item-id}/permissions

using System; using System.Threading.Tasks; using Azure; using Azure.Search.Documents; using Azure.Search.Documents.Models; class Program { static async Task Main(string[] args) { string searchServiceName = "<YourSearchServiceName>"; string indexName = "<YourIndexName>"; string apiKey = "<YourAdminApiKey>"; string userPrincipalName = "<UserPrincipalName>"; // User Identity // Initialize Cognitive Search Client var searchClient = new SearchClient( new Uri($"https://{searchServiceName}.search.windows.net"), indexName, new AzureKeyCredential(apiKey) ); // Search Query with User Permissions var options = new SearchOptions { Filter = $"permissions/any(p: p eq '{userPrincipalName}')", Size = 10 }; var results = await searchClient.SearchAsync<SearchDocument>("*", options); // Display Accessible Documents Console.WriteLine("Accessible Documents:"); foreach (var result in results.GetResults()) { Console.WriteLine(result.Document["name"]); } } }
