Description

CelerSearch routes WordPress search through Meilisearch. Sub-50ms responses, typo tolerance, autocomplete, highlighting, and full WooCommerce support — with an admin UI built for day-to-day use, not just setup.

🔍 Search

  • Millisecond results on any site size
  • Typo tolerance and stemming out of the box
  • Live autocomplete as users type
  • Match highlighting on titles and excerpts
  • Category, tag, and custom-taxonomy filtering
  • Custom search results pages via Views + block/shortcode
  • Native WordPress search fallback when Meilisearch is unreachable

🗂 Indexing

  • Posts, pages, any custom post type
  • WooCommerce products (including variations) and orders
  • Real-time sync on publish, update, trash, and watched meta changes
  • Manual rebuild with configurable batch size
  • Per-index searchable, filterable, sortable attributes + synonyms — all editable in the admin
  • Content splitting for long posts (configurable; Meilisearch deduplicates results)

🌐 Where search runs

  • Frontend site search (replace the default results page with a custom View)
  • Admin list search (posts, products, media)
  • REST API search (headless/decoupled setups)
  • AJAX-faceted WooCommerce shop & archive filters

🎯 Use cases

  • WooCommerce stores with thousands of orders — native admin order search slows to a crawl and misses matches as the orders table grows. Enable the “WooCommerce Admin Orders Search” area and lookups stay instant at any scale.
  • Product catalogs with rich attributes — drive shop and category archives with AJAX-faceted filters for color, size, brand, price, plus typo-tolerant keyword search.
  • Content-heavy sites (news, blogs, documentation) — replace the frontend search with live autocomplete and fuzzy matching so readers find posts by typing a few characters.
  • Custom post types at scale — directories, job boards, listings. Native WP search is a slow LIKE '%…%' across a handful of columns; CelerSearch indexes every field and ranks by relevance.

🧑‍💻 Developer-friendly

  • 40+ filter hooks across indexing, search, and results
  • Extend with your own index types (celersearch_supported_indices)
  • Custom search-area types (celersearch_area_types) for BuddyPress, LearnDash, etc.
  • Taxonomy-aware queries translate WP_Query tax_query to the engine filter syntax

Do I need my own Meilisearch server?

Yes. Two options:

  • Self-host on your VPS — free, but you handle updates, backups, and SSL. Upstream guide.
  • Managed at celersearch.com — from $10/mo, provisioned in seconds, updates and backups handled.

Does it work with WooCommerce?

Yes. Dedicated Products and Orders index types, plus AJAX-faceted shop & archive filters.

Will it slow down my site?

No. Search queries go to Meilisearch, which responds in under 50ms.

What if Meilisearch goes down?

With fallback enabled (default), search reverts to native WordPress search automatically.

Can I disable content splitting for large posts?

Yes. Open CelerSearch Indices, edit the index, and toggle Content Splitting (chunk size is configurable per index).

For site-wide overrides you can also set these in wp-config.php:

define( 'CELERSEARCH_SPLIT_POSTS', false );
define( 'CELERSEARCH_CONTENT_MAX_SIZE', 3000 );

Rebuild the affected indices after changing either.

How do I replace the default search results page?

  1. CelerSearch Views — create a View, pick an index, configure behavior.
  2. Create a WordPress page and embed the View via the CelerSearch block or [celersearch] shortcode.
  3. CelerSearch Settings Search Areas — on “WordPress Public Search”, enable “Replace Search Results Page” and pick the page.

What’s the difference between Search Areas and Views?

They solve different problems and often work together.

  • Search Areas (Settings Search Areas) intercept WordPress search where it already happens — the frontend search, admin list search, REST API search, WooCommerce shop filters — and route it through Meilisearch. No template changes; you pick which index each context uses.
  • Views (CelerSearch Views) are a UI primitive for building custom search experiences you embed via the CelerSearch block or the [celersearch] shortcode. A View bundles the input, autocomplete, filters, results layout, and sorting as one configurable unit you drop onto any page or widget area.

Typical setup uses both: create a View-powered search page, then enable “Replace Search Results Page” on the WordPress Public Search area and point it at that page — the Search Area handles the interception, the View renders the page.
