Search providers

AvantiPoint Packages supports several search backends. Search.Type selects how queries run (ISearchService). ISearchIndexer.Key tracks which external index last wrote each package version (Package.IndexedWith).

Search types

Search.Type	Query service	Indexer	Indexer key
Database (default)	DatabaseSearchService	NullSearchIndexer (no external index)	Null
Null	NullSearchService	NullSearchIndexer	Null
Elasticsearch	ElasticsearchSearchService	ElasticsearchSearchIndexer	Elasticsearch
OpenSearch	OpenSearchSearchService (AWS)	OpenSearchSearchIndexer	OpenSearch
AzureSearch	AzureSearchService	AzureSearchIndexer	AzureSearch

When to use an external index

• Database — simplest deployment; search runs against SQL with no extra infrastructure.
• Elasticsearch / OpenSearch / Azure AI Search — better full-text relevance, lower database load on large feeds, and horizontal scaling of search workloads.

Startup reconciliation

When an external indexer is active, a background service reindexes packages whose IndexedWith is null or does not match the current indexer key. The API starts immediately; search results may be incomplete until reconciliation finishes.

NullSearchIndexer (Database and Null search types) skips reconciliation entirely.

Configuration

{
  "Feed": {
    "Search": {
      "Type": "Elasticsearch",
      "ReconcileBatchSize": 100
    }
  }
}
