Criar uma base de dados de conhecimento no Pesquisa de IA do Azure 

• O pacote de versão prévia Azure.Search.Documents mais recente: dotnet add package Azure.Search.Documents --prerelease

• O pacote de versão prévia azure-search-documents mais recente: pip install --pre azure-search-documents

• A versão 2025-11-01-preview das APIs REST do Serviço de Pesquisa.

Execute o código a seguir para listar as bases de dados de conhecimento existentes por nome.

// List knowledge bases by name
  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}");
  }

Execute o código a seguir para listar as bases de dados de conhecimento existentes por nome.

# List knowledge bases by name
from azure.core.credentials import AzureKeyCredential
from azure.search.documents.indexes import SearchIndexClient

index_client = SearchIndexClient(endpoint = "search_url", credential = AzureKeyCredential("api_key"))

for kb in index_client.list_knowledge_bases():
    print(f"  - {kb.name}")
