You built an app with Claude, ChatGPT, Bolt, or Lovable that has content or data, and users need to find specific things within it. Products, articles, users, records. Right now the only way to find something is to scroll through everything. You want a search box. Adding search to a web app is one of those features that ranges from five minutes of work to weeks of engineering depending on how you do it. Here is the full picture and the right approach for where you are.
The Three Levels of Search
Level 1: Database search. Your database already has the data. Most databases can search through it with a simple query. This is the right starting point for almost every vibe-coded app.
Level 2: Full-text search. More powerful than basic database queries. Finds results even when the search term is not an exact match. Handles typos, partial words, and relevance ranking.
Level 3: Dedicated search service. Tools like Algolia or Typesense that are built specifically for search. Extremely fast, highly relevant results, handles large volumes. Overkill for most early-stage apps.
Start at Level 1. Move up only when Level 1 stops meeting your needs.
Level 1: Search Using Your Database
If you use Supabase, you can add a basic search with a few lines of SQL using the ILIKE operator. ILIKE means “case-insensitive match” and finds any records where the searched field contains the search term.
Ask your AI: “I want to add search to my app. Users should be able to search [describe what they are searching, e.g. products by name, articles by title or content]. I use Supabase. Can you add a search endpoint to my backend and a search input to my frontend that filters results as the user types?”
Your AI will write the database query, the backend route that accepts a search term, and the frontend search input that sends queries and displays results.
Level 2: Full-Text Search
If you need more powerful search, Supabase has built-in full-text search using PostgreSQL’s text search capabilities. It handles stemming (finding “run” when searching “running”), relevance ranking, and searching across multiple fields.
Ask your AI: “I want to upgrade my app’s search to use Supabase full-text search so it handles partial matches and is more relevant. Can you update my search implementation to use PostgreSQL full-text search?”
For Firebase users, full-text search is not built in. The recommended approach is to use Algolia’s Firebase extension, which automatically syncs your Firestore data to Algolia for searching.
Level 3: Algolia (When You Need the Best)
Algolia is the gold standard for search in apps. It provides instant results, typo tolerance, relevance ranking, and a hosted search index. The free tier covers up to ten thousand search requests per month.
Ask your AI: “I want to add Algolia search to my app. Can you help me set up the Algolia index, write the code to sync my data to Algolia, and add a search component to my frontend?”
Making Search Feel Good
Beyond the backend, good search has a few frontend qualities that make a significant difference:
Search as you type rather than requiring the user to press Enter. Results that highlight the matched term. A clear empty state when nothing matches. A loading indicator while results are fetching.
Ask your AI: “Can you improve my search UI to show results as the user types, highlight the matching text in results, and show a friendly empty state when there are no results?”
The One Thing to Remember
Search has three levels: database queries for basic needs, full-text search for relevance and typo handling, and dedicated services like Algolia for scale. Start with your database. Supabase full-text search handles most apps beyond the basics. Only add Algolia when you need the best possible search experience at scale.
