Module query 

Query routing and intent detection for intelligent search.

This module provides query analysis capabilities to determine the best search strategy based on user intent. It helps route queries to the appropriate search backend or external tools like loctree.

Architecture

Query -> [Intent Detection] -> QueryIntent
      -> [Query Router] -> RoutingDecision
                           ├── Temporal → Date filtering + timestamp priority
                           ├── Structural → Delegate to loctree
                           ├── Semantic → Pure vector search
                           ├── Exact → BM25 keyword match
                           └── Hybrid → Vector + BM25 fusion

Usage

use rust_memex::query::{detect_intent, QueryIntent, QueryRouter};

// Quick intent detection
let intent = detect_intent("when did we buy dragon");
assert!(matches!(intent, QueryIntent::Temporal));

// Full routing with recommendations
let router = QueryRouter::new();
let decision = router.route("what imports main.rs");
if let Some(suggestion) = decision.loctree_suggestion {
    println!("Suggested: {}", suggestion.command);
}
