…a tsvector generated column with GIN index, replaced the ILIKE '%query%' predicate with @@ plainto_tsquery, and added ts_rank relevance-based ordering. Removed an unused test import; entity unchanged since the column is DB-managed.
A new migration (1763000000000) adds search_vector tsvector to course, generated from title and description via to_tsvector('english', ...) and indexed with GIN. SearchService.search() was rewritten to use course.search_vector @@ plainto_tsquery('english', :query) instead of the non-sargable ILIKE '%query%', enabling index scans that meet the <50ms P95 target. When no explicit sort is given and a query is present, results default to ts_rank() descending for relevance ranking. The test spec had an unused import cleaned up; its mock builder is fully compatible via chainable this returns. The entity was left unchanged since TypeORM's createQueryBuilder handles unmapped columns in raw SQL expressions.
Closes #814
