    @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:


    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.



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

    More info here:

    Sample code snippet here:

    Operation<AnalyzeResult> operation = await client.AnalyzeDocumentAsync(
        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.
