Execute a Query using a dialog expression

This example shows how you can search documents using a DialogExpression. If you don't need all the document's data it's recommended to use GetDocumentsTableResult(Dialog, DialogExpression) extension method to get a DocumentsQueryTableResult for more optimized result.

Use a dialog expression

C#

using System;
using System.Collections.Generic;
using System.Linq;
using DocuWare.Platform.ServerClient;

namespace DocuWare.PlatformClientExamples
{
    static partial class Examples
    {
        public static DocumentsQueryResult RunQuery(Dialog dialog)
        {
            var q = new DialogExpression()
            {
                Operation = DialogExpressionOperation.And,
                Condition = new List<DialogExpressionCondition>()
                {
                    DialogExpressionCondition.Create("SENDER", "A", "ZZZZ" )
                },
                Count = 100,
                SortOrder = new List<SortedField> 
                { 
                    SortedField.Create("DWSTOREDATETIME", SortDirection.Desc)
                }
            };

            var queryResult = dialog.GetDocumentsResult(q);
            foreach (var d in queryResult.Items)
            {
                Console.WriteLine("Hit {0}: \"{1}\" on {2}", d.Id, (d["SENDER"].Item as string) ?? "-", d.CreatedAt);
            }
            return queryResult;
        }

    }
}

Use a dialog expression asynchronously

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using DocuWare.Platform.ServerClient;

namespace DocuWare.PlatformClientExamples
{
    static partial class ExamplesAsync
    {
        public static async Task<DocumentsQueryResult> RunQueryAsync(Dialog dialog)
        {
            var q = new DialogExpression()
            {
                Operation = DialogExpressionOperation.And,
                Condition = new List<DialogExpressionCondition>()
                {
                    DialogExpressionCondition.Create("SENDER", "A", "ZZZZ" )
                },
                Count = 100,
                SortOrder = new List<SortedField> 
                { 
                    SortedField.Create("DWSTOREDATETIME", SortDirection.Desc)
                }
            };

            DocumentsQueryResult queryResult = await dialog.GetDocumentsResultAsync(q).ConfigureAwait(false);
            foreach (var d in queryResult.Items)
            {
                Console.WriteLine("Hit {0}: \"{1}\" on {2}", d.Id, (d["SENDER"].Item as string) ?? "-", d.CreatedAt);
            }

            return queryResult;
        }

    }
}

Use a dialog expression to get table result asynchronously

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using DocuWare.Platform.ServerClient;

namespace DocuWare.PlatformClientExamples
{
    static partial class ExamplesAsync
    {
        public static async Task<DocumentsQueryTableResult> RunQueryForTableAsync(Dialog dialog)
        {
            var q = new DialogExpression()
            {
                Operation = DialogExpressionOperation.And,
                Condition = new List<DialogExpressionCondition>()
                {
                    DialogExpressionCondition.Create("SENDER", "A", "ZZZZ" )
                },
                Count = 100,
                SortOrder = new List<SortedField> 
                { 
                    SortedField.Create("DWSTOREDATETIME", SortDirection.Desc)
                }
            };

            DocumentsQueryTableResult queryResult = await dialog.GetDocumentsTableResultAsync(q).ConfigureAwait(false);
            var senderIdx = 
                queryResult
                    .Headers
                    .Select(
                        (v, i) 
                            => new { header = v, index = i })
                    .First(h => h.header.FieldName == "SENDER")
                    .index;

            foreach (var r in queryResult.Rows)
            {
                Console.WriteLine(@"Hit {0}: ""{1}""", r.Id, (r.Items[senderIdx] as string) ?? "-");
            }

            return queryResult;
        }

    }
}
