# Algolia Search Integration

## Patterns

### React InstantSearch with Hooks

Modern React InstantSearch setup using hooks for type-ahead search.

Uses react-instantsearch-hooks-web package with algoliasearch client.
Widgets are components that can be customized with classnames.

Key hooks:
- useSearchBox: Search input handling
- useHits: Access search results
- useRefinementList: Facet filtering
- usePagination: Result pagination
- useInstantSearch: Full state access


### Next.js Server-Side Rendering

SSR integration for Next.js with react-instantsearch-nextjs package.

Use <InstantSearchNext> instead of <InstantSearch> for SSR.
Supports both Pages Router and App Router (experimental).

Key considerations:
- Set dynamic = 'force-dynamic' for fresh results
- Handle URL synchronization with routing prop
- Use getServerState for initial state


### Data Synchronization and Indexing

Indexing strategies for keeping Algolia in sync with your data.

Three main approaches:
1. Full Reindexing - Replace entire index (expensive)
2. Full Record Updates - Replace individual records
3. Partial Updates - Update specific attributes only

Best practices:
- Batch records (ideal: 10MB, 1K-10K records per batch)
- Use incremental updates when possible
- partialUpdateObjects for attribute-only changes
- Avoid deleteBy (computationally expensive)
