Perform fast lexical, filename, property, or phrase search across a DeepOrbit vault. Use for exact names, identifiers, tags, error text, regex-like lookup intent, or when semantic retrieval is unnecessary or unavailable.
This uses the zero-dependency local SQLite FTS index and automatically reconciles synced, changed, renamed, and deleted Markdown files. If SQLite FTS is unavailable, the core falls back to direct case-insensitive scanning.
Return vault-relative paths, note titles, and short snippets. Do not modify notes during search.
