🔍 Implement Full‐Text Search with Tsvector and Indexes​

Leverage full‐text capabilities by storing tsvector columns and indexing them. Use to_tsvector() and to_tsquery() or plainto_tsquery() for flexible searches.

ALTER TABLE articles ADD COLUMN content_tsv tsvector;
UPDATE articles SET content_tsv = to_tsvector('english', title || ' ' || body);
CREATE INDEX idx_articles_tsv ON articles USING GIN (content_tsv);

SELECT id, title
FROM articles
WHERE content_tsv @@ plainto_tsquery('english', 'database optimization');

Triggers can keep content_tsv in sync on INSERT/UPDATE, enabling lightning‐fast search queries.
