Interface SearchClient

All Superinterfaces:
AutoCloseable
All Known Implementing Classes:
InMemorySearchStore, WebSocketSearchClient
public interface SearchClient extends AutoCloseable
Low-level interface for interacting with a search and indexing service in Fluxzero.

The SearchClient operates exclusively on serialized forms of documents (see SerializedDocument) and search-related requests. It is the primary interface used by internal components like DocumentStore to execute actual search operations against a backing implementation (e.g., Fluxzero Runtime or an in-memory search engine for testing).
