@Khadija Alaqra Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

Yes, the SDK has the support for QueryFields feature.

The following add-on capabilities are available for2024-02-29-preview and later releases:

• keyValuePairs
• queryFields

.

Please note that Query fields: query fields are reintroduced as a premium add-on feature. When the DocumentAnalysisFeature.QueryFields argument is passed to a document analysis request, the service will further extract the values of the fields specified via the parameter queryFields to supplement any existing fields defined by the model as fallback.

.

Suggestions:

You need to use one of the overloads of DocumentIntelligenceClient.AnalyzeDocumentAsync Method by passing the DocumentAnalysisFeature.QueryFields Property.

More info here: https://learn.microsoft.com/en-us/dotnet/api/azure.ai.documentintelligence.documentanalysisfeature.queryfields?view=azure-dotnet-preview

Sample code snippet here:

Operation<AnalyzeResult> operation = await client.AnalyzeDocumentAsync(
    WaitUntil.Completed,
    "prebuilt-receipt",
    new AnalyzeDocumentContent
    {
        Base64Source = new BinaryData(dbScanToWs.RelatedPDFs[i])
    },
    queryFields: new List<string> { "TaxDetails_TaxAmount", "TaxDetails_TaxNetPercentage" },
    features: new List<DocumentAnalysisFeature> { DocumentAnalysisFeature.QueryFields });
AnalyzeResult receipts = operation.Value;

Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
