Utilizing Azure Cognitive Search in Your Utility

Let’s create a easy .NET utility that makes use of Azure Cognitive Search to index and search paperwork.

Step 1. Create a .NET Console Utility

First, create a brand new .NET console utility.

dotnet new console -n AzureCognitiveSearchDemo
cd AzureCognitiveSearchDemo

Step 2. Set up Required Packages

Set up the Azure Cognitive Search SDK.

dotnet add package deal Azure.Search.Paperwork

Step 3. Implement the Code

Create a category `SearchService` to work together with the Azure Cognitive Search service.

utilizing Azure;
utilizing Azure.Search.Paperwork;
utilizing Azure.Search.Paperwork.Indexes;
utilizing Azure.Search.Paperwork.Indexes.Fashions;
utilizing Azure.Search.Paperwork.Fashions;
utilizing System;
utilizing System.Collections.Generic;
utilizing System.Threading.Duties;

public class SearchService
{
    personal readonly string _serviceName;
    personal readonly string _apiKey;
    personal readonly string _indexName;
    personal readonly SearchClient _searchClient;
    personal readonly SearchIndexClient _indexClient;

    public SearchService(string serviceName, string apiKey, string indexName)
    {
        _serviceName = serviceName;
        _apiKey = apiKey;
        _indexName = indexName;
        string serviceEndpoint = $"https://{_serviceName}.search.home windows.web";
        _indexClient = new SearchIndexClient(new Uri(serviceEndpoint), new AzureKeyCredential(_apiKey));
        _searchClient = new SearchClient(new Uri(serviceEndpoint), _indexName, new AzureKeyCredential(_apiKey));
    }

    public async Activity CreateIndexAsync()
    {
        var fieldBuilder = new FieldBuilder();
        var searchFields = fieldBuilder.Construct(typeof(Doc));

        var definition = new SearchIndex(_indexName, searchFields);

        await _indexClient.CreateOrUpdateIndexAsync(definition);
    }

    public async Activity IndexDocumentsAsync(IEnumerable<Doc> paperwork)
    {
        var batch = IndexDocumentsBatch.Add(paperwork);
        await _searchClient.IndexDocumentsAsync(batch);
    }

    public async Activity SearchAsync(string question)
    {
        var choices = new SearchOptions
        {
            IncludeTotalCount = true,
            Filter = "",
            OrderBy = new Listing<string> { "rating desc" }
        };

        SearchResults<Doc> outcomes = await _searchClient.SearchAsync<Doc>(question, choices);

        Console.WriteLine($"Complete Paperwork Discovered: {outcomes.TotalCount}");

        foreach (SearchResult<Doc> end in outcomes.GetResults())
        {
            Console.WriteLine($"Doc: {outcome.Doc.Id} - {outcome.Doc.Content material}");
        }
    }
}

public class Doc
{
    [SimpleField(IsKey = true, IsFilterable = true)]
    public string Id { get; set; }

    [SearchableField(IsFilterable = true, IsSortable = true)]
    public string Content material { get; set; }
}

Replace the `Program.cs` file to make use of the `SearchService`.

utilizing System;
utilizing System.Collections.Generic;
utilizing System.Threading.Duties;

namespace AzureCognitiveSearchDemo
{
    class Program
    {
        static async Activity Principal(string[] args)
        {
            Console.WriteLine("Enter your Azure Cognitive Search service title:");
            var serviceName = Console.ReadLine();

            Console.WriteLine("Enter your Azure Cognitive Search API key:");
            var apiKey = Console.ReadLine();

            Console.WriteLine("Enter the index title:");
            var indexName = Console.ReadLine();

            var searchService = new SearchService(serviceName, apiKey, indexName);

            await searchService.CreateIndexAsync();

            var paperwork = new Listing<Doc>
            {
                new Doc { Id = "1", Content material = "Azure Cognitive Search offers highly effective search capabilities." },
                new Doc { Id = "2", Content material = "Leveraging AI and machine studying in search companies." }
            };

            await searchService.IndexDocumentsAsync(paperwork);

            Console.WriteLine("Enter a search question:");
            var question = Console.ReadLine();

            await searchService.SearchAsync(question);
        }
    }
}

Operating the Utility

Run the appliance utilizing the next command.

dotnet run

When prompted, enter your Azure Cognitive Search service title, API key, index title, and a search question. The appliance will then show the search outcomes.
