Crestapps Core Elasticsearch

CrestApps.Core Elasticsearch - Prompt Templates

Add Elasticsearch

You are a CrestApps.Core expert. Configure CrestApps.Core.Elasticsearch with CrestApps.Core.AI.Elasticsearch through the indexing builder.

builder.Services.AddCrestAppsCore(crestApps => crestApps
    .AddIndexingServices(indexing => indexing
        .AddElasticsearch(
            builder.Configuration.GetSection("CrestApps:Search:Elasticsearch"),
            search => search
                .AddAIDocuments()
                .AddAIDataSources()
                .AddAIMemory())
    )
);

AddCoreElasticsearchServices(...) only registers the connection options, IElasticsearchClientFactory, the default ElasticsearchClient, and the provider-keyed indexing primitives. It does not add AI document, data-source, or memory support. For lower-level composition, call the matching AddCoreElasticsearchAIDocumentSource(), AddCoreElasticsearchAIDataSource(), and/or AddCoreElasticsearchAIMemorySource() methods after registering the primitive services.

Configuration

{
  "CrestApps": {
    "Search": {
      "Elasticsearch": {
        "Url": "https://localhost:9200",
        "AuthenticationType": "Basic",
        "Username": "elastic",
        "Password": "use-a-secret",
        "IndexPrefix": "app_"
      }
    }
  }
}

ElasticsearchConnectionOptions supports Url, CloudId, AuthenticationType, Username, Password, ApiKey, Base64ApiKey, ApiKeyId, CertificateFingerprint, and IndexPrefix. IndexPrefix is prepended to framework-managed index names. Configure either endpoint or cloud deployment credentials as required and keep secrets out of checked-in settings.

What Each AI Option Adds

• AddAIDocuments() adds an AIDocuments index-profile source, its profile handler, and keyed IVectorSearchService.
• AddAIDataSources() adds a DataSource index-profile source, the shared data-source RAG stack, and a keyed ElasticsearchAIDataSourceSourceHandler.
• AddAIMemory() adds an AIMemory index-profile source, its profile handler, and keyed IMemoryVectorSearchService.

The primitive package registers keyed IDataSourceContentManager, IDataSourceDocumentReader, IODataFilterTranslator, ISearchIndexManager, and ISearchDocumentManager. These are provider-keyed services, not default implementations.

External Sources and Indexing

AIDataSource records with source type Elasticsearch can read an externally managed index. Their source credentials and index name are independent from the shared backend that stores CrestApps RAG chunks. After external index changes, call IAIDataSourceChangeNotifier.

AddAIDataSources() composes the shared asynchronous synchronization stack: IAIDataSourceIndexingQueue, IAIDataSourceIndexingService, catalog and document handlers, AIDataSourceIndexingBackgroundService, AIDataSourceAlignmentBackgroundService, and DataSourceSearchIndexProfileHandler.
