Language routing: The language-specific handoff in the frontmatter above is a variant edge. If the user's language is known, route directly to the matching search-<lang> skill. If unknown, ask before routing.

Couchbase Search — Concepts

Couchbase provides two complementary search capabilities built on the same index and query infrastructure:

• Full-Text Search (FTS) — text analysis, fuzzy matching, phrase search, geospatial
• Vector Search — nearest-neighbour semantic search over embedding vectors

Both use the same index service (port 8094), the same SDK API (cluster.search() / cluster.searchQuery()), and can be combined in a single hybrid search query.

For index prerequisites, query types, hybrid search, RYOW consistency, Flex Index, and pagination, see shared/server/search-concepts.md.
