Azure Search Integration

A library that provides integration with Azure Cognitive Search, enabling full-text search capabilities in your applications.

Intended Usage

Use this library when you need to implement advanced search functionality using Azure Cognitive Search, including indexing, searching, filtering, faceting, and suggestions.

Installation

Add the package to your project:

dotnet add package Enigmatry.Entry.AzureSearch

Usage Example

Configuring a searchable model:

using Azure.Search.Documents.Indexes; using Azure.Search.Documents.Indexes.Models; // Define a searchable model public class ProductSearchModel { [SimpleField(IsKey = true)] public string Id { get; set; } = string.Empty; [SearchableField(IsSortable = true)] public string Name { get; set; } = string.Empty; [SearchableField] public string Description { get; set; } = string.Empty; [SimpleField(IsSortable = true, IsFacetable = true, IsFilterable = true)] public decimal Price { get; set; } [SimpleField(IsFacetable = true, IsFilterable = true)] public string Category { get; set; } = string.Empty; [SimpleField(IsFilterable = true)] public bool IsAvailable { get; set; } }

Using the search service:

using System.Threading.Tasks; using System.Collections.Generic; using Azure.Search.Documents.Models; using Enigmatry.Entry.AzureSearch; using Enigmatry.Entry.AzureSearch.Abstractions; public class ProductSearchService { private readonly ISearchService<ProductSearchModel> _searchService; public ProductSearchService(ISearchService<ProductSearchModel> searchService) { _searchService = searchService; } public async Task UpdateProductAsync(ProductSearchModel product) { // Add/Update a single document to the index await _searchService.UpdateDocument(product); } public async Task UpdateProductsAsync(IEnumerable<ProductSearchModel> products) { // Add/Update multiple documents to the index await _searchService.UpdateDocuments(products); } public async Task<SearchResponse<ProductSearchModel>> SearchProductsAsync(string searchText) { // Create search options using the Azure SDK var options = new Azure.Search.Documents.SearchOptions { Filter = "IsAvailable eq true", OrderBy = { "Price asc" }, IncludeFacets = true, Facets = { "Category" }, Size = 10 }; // Use SearchText to properly format and escape search terms var formattedSearchText = SearchText.AsEscaped(searchText); // Execute the search and get results return await _searchService.Search(formattedSearchText, options); } public async Task<SearchResponse<ProductSearchModel>> SearchProductsWithPhraseAsync(string searchText) { // Use phrase search for exact matching (wrapped in quotes) var phraseSearchText = SearchText.AsPhraseSearch(searchText); return await _searchService.Search(phraseSearchText); } }

Configuration Example

{ "SearchSettings": { "SearchServiceEndPoint": "https://myapp-search.search.windows.net", "ApiKey": "your-azure-search-api-key" } }

Dependency Injection Example

using Enigmatry.Entry.AzureSearch.Extensions; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Configuration; public class Startup { public void ConfigureServices(IServiceCollection services, IConfiguration configuration) { // Add Azure Search core services services.AddAzureSearch(configuration.GetSection("SearchSettings")) // Register a document type with a specific index name .AddDocument<ProductSearchModel>("products"); // Alternatively, configure settings in code // services.AddAzureSearch(options => { // options.SearchServiceEndPoint = new Uri("https://myapp-search.search.windows.net"); // options.ApiKey = "your-azure-search-api-key"; // }).AddDocument<ProductSearchModel>(); } }
