Perform Case-Insensitive Full-Text Search
Implement basic case-insensitive full-text search across multiple text columns in your database, leveraging the `ILIKE` operator (PostgreSQL) for flexible pattern matching.
SELECT id, title, content
FROM articles
WHERE title ILIKE '%web development%'
OR content ILIKE '%web development%';
How it works: This query shows how to perform a case-insensitive search for a specific term across multiple text columns. The `ILIKE` operator, common in PostgreSQL, provides case-insensitivity when pattern matching with wildcards (`%`). This allows web applications to deliver flexible search capabilities without requiring users to match exact case, enhancing user experience.
