Create a blob knowledge source from Azure Blob Storage and ADLS Gen2

Get a list of all knowledge bases on your search service.

using Azure.Search.Documents.Indexes;

var indexClient = new SearchIndexClient(new Uri(searchEndpoint), credential);
var knowledgeBases = indexClient.GetKnowledgeBasesAsync();

Console.WriteLine("Knowledge Bases:");

await foreach (var kb in knowledgeBases)
{
    Console.WriteLine($"  - {kb.Name}");
}

An example response might look like the following:

 Knowledge Bases:
   - earth-knowledge-base
   - hotels-sample-knowledge-base
   - my-demo-knowledge-base

Get an individual knowledge base definition to check for knowledge source references.

using Azure.Search.Documents.Indexes;
using System.Text.Json;

var indexClient = new SearchIndexClient(new Uri(searchEndpoint), credential);

// Specify the knowledge base name to retrieve
string kbNameToGet = "earth-knowledge-base";

// Get a specific knowledge base definition
var knowledgeBaseResponse = await indexClient.GetKnowledgeBaseAsync(kbNameToGet);
var kb = knowledgeBaseResponse.Value;

// Serialize to JSON for display
string json = JsonSerializer.Serialize(kb, new JsonSerializerOptions { WriteIndented = true });
Console.WriteLine(json);

An example response might look like the following:

 {
   "Name": "earth-knowledge-base",
   "KnowledgeSources": [
     {
       "Name": "earth-knowledge-source"
     }
   ],
   "Models": [
     {}
   ],
   "RetrievalReasoningEffort": {},
   "OutputMode": {},
   "ETag": "\u00220x8DE278629D782B3\u0022",
   "EncryptionKey": null,
   "Description": null,
   "RetrievalInstructions": null,
   "AnswerInstructions": null
 }

Either delete the knowledge base or update the knowledge base to remove the knowledge source if you have multiple sources. This example shows deletion.

using Azure.Search.Documents.Indexes;
var indexClient = new SearchIndexClient(new Uri(searchEndpoint), credential);

await indexClient.DeleteKnowledgeBaseAsync(knowledgeBaseName);
System.Console.WriteLine($"Knowledge base '{knowledgeBaseName}' deleted successfully.");

Delete the knowledge source.

await indexClient.DeleteKnowledgeSourceAsync(knowledgeSourceName);
System.Console.WriteLine($"Knowledge source '{knowledgeSourceName}' deleted successfully.");

# Get knowledge bases
import requests
import json

endpoint = "{search_url}/knowledgebases"
params = {"api-version": "2025-11-01-preview", "$select": "name"}
headers = {"api-key": "{api_key}"}

response = requests.get(endpoint, params = params, headers = headers)
print(json.dumps(response.json(), indent = 2))

An example response might look like the following:
