Enhanced search with grammar

Search using structured grammar queries with automatic query routing. The enhanced endpoint analyzes the query and routes it to the optimal search strategy:

• Grammar (tool:midjourney AND tag:hero) — structured field:value filters, routed to SQL
• Semantic (a dreamy landscape at sunset) — natural language, routed to vector similarity
• Hybrid (cyberpunk tool:midjourney) — combines semantic + grammar filters
• Simple (hero banner) — basic text matching

This endpoint is recommended for most use cases — it handles query classification automatically. Use /assets/search for explicit control or /assets/search-semantic for pure vector search.

See the SearchGrammarReference schema for all available grammar fields.
