Unleashing the Power of Custom Sorting in Azure Search Service using .NET 8 Web API

Are you tired of being limited by the default sorting options in Azure Search Service? Do you want to take your search functionality to the next level by implementing custom sorting tailored to your application’s specific needs? Look no further! In this comprehensive guide, we’ll explore how to implement custom sorting for Azure Search Service in .NET 8 Web API, empowering you to create a more engaging and personalized user experience.

The Importance of Custom Sorting in Azure Search Service

Azure Search Service is a powerful cloud-based search service that enables you to add search functionality to your applications. While it provides a robust set of features, its default sorting options might not always meet the specific requirements of your application. This is where custom sorting comes into play. By implementing custom sorting, you can:

• Improve search relevance by prioritizing specific fields or criteria
• Enhance user experience by providing more intuitive and personalized search results
• Increase the effectiveness of your search functionality by adapting to your application’s unique needs

Prerequisites and Requirements

Before diving into the implementation, ensure you have the following:

1. A .NET 8 Web API project set up with Azure Search Service integration
2. An Azure Search Service instance with a configured index and data source
3. Basic understanding of C# and .NET 8 Web API development

Step 1: Create a Custom Sorting Class

To implement custom sorting, you need to create a custom sorting class that will define the sorting logic. Create a new class in your .NET 8 Web API project and name it CustomSorter.cs.

public class CustomSorter
{
    public string FieldName { get; set; }
    public SortOrder SortOrder { get; set; }
}

public enum SortOrder
{
    Ascending,
    Descending
}

This class will hold the field name and sort order for each custom sorting criterion.

Step 2: Create a Custom Sorting Service

Create a new service class that will encapsulate the custom sorting logic. Name it CustomSortingService.cs.

public class CustomSortingService
{
    private readonly ISearchIndexClient _searchIndexClient;

    public CustomSortingService(ISearchIndexClient searchIndexClient)
    {
        _searchIndexClient = searchIndexClient;
    }

    public async Task<SearchResults> SearchAsync(SearchRequest searchRequest)
    {
        // Initialize the search parameters
        var sp = new SearchParameters
        {
            Select = new[] { "*" },
            QueryType = QueryType.Full,
            Top = 10
        };

        // Add custom sorting to the search parameters
        foreach (var sorter in searchRequest.Sorters)
        {
            sp.AddSort(sorter.FieldName, sorter.SortOrder == SortOrder.Ascending);
        }

        // Execute the search
        var result = await _searchIndexClient.Documents.SearchAsync(searchRequest.Query, sp);

        return result;
    }
}

This service class takes an instance of ISearchIndexClient in its constructor, which will be used to interact with the Azure Search Service. The SearchAsync method executes the search query with the custom sorting parameters.

Step 3: Integrate Custom Sorting with Azure Search Service

In your .NET 8 Web API controller, inject the CustomSortingService instance and use it to execute the search query.

[ApiController]
[Route("api/[controller]")]
public class SearchController : ControllerBase
{
    private readonly CustomSortingService _customSortingService;

    public SearchController(CustomSortingService customSortingService)
    {
        _customSortingService = customSortingService;
    }

    [HttpPost]
    public async Task<IActionResult> SearchAsync(SearchRequest searchRequest)
    {
        var result = await _customSortingService.SearchAsync(searchRequest);

        return Ok(result);
    }
}

In this example, the SearchController uses the CustomSortingService to execute the search query with custom sorting.

Step 4: Consume Custom Sorting in Your Frontend

In your frontend application, create a search request object that includes the custom sorting criteria.

var searchRequest = {
    Query: "search query",
    Sorters: [
        { FieldName: "rating", SortOrder: "Descending" },
        { FieldName: "price", SortOrder: "Ascending" }
    ]
};

Send this request to your .NET 8 Web API controller, which will execute the search query with custom sorting.
