//! Retrieval strategies for different query types.
//!
//! This module provides several retrieval strategies:
//!
//! - **KeywordStrategy**: Fast keyword matching using TF-IDF
//! - **SemanticStrategy**: Embedding-based semantic similarity
//! - **LlmStrategy**: LLM-powered reasoning with ToC context
//! - **HybridStrategy**: BM25 pre-filter + LLM refinement (recommended)
//! - **CrossDocumentStrategy**: Multi-document retrieval with result aggregation
//! - **PageRangeStrategy**: Filter by page range before retrieval
