Performs fast full-text search over code IDs and descriptions.

Availability: This endpoint is only available for built-in code systems. Custom code systems uploaded via /construe/upload are not indexed for full-text search and will return empty results. Use /search/semantic to search custom code systems.

When to use: Best for autocomplete UIs, code lookup, or when users know part of the code ID or specific keywords. Fast response times suitable for typeahead interfaces.

Features:

• Substring matching on code IDs (e.g., "11.65" finds "E11.65")
• Typo tolerance on descriptions (not on code IDs)
• Fast response times (~10-50ms)

Examples:

• Query "E11" finds all codes starting with E11 (diabetes codes)
• Query "diabtes" (typo) still finds "diabetes" codes

Trade-offs: Faster than semantic search, but only matches keywords/substrings. Won't find conceptually related codes with different terminology.

See also: /search/semantic for finding conceptually similar codes.
