NivoSearch – Ajax Search for WooCommerce

NivoSearch is a WooCommerce Ajax Search plugin that helps customers find products as they type, without reloading the page. This WooCommerce Search Plugin provides live product suggestions, typo correction, fuzzy matching, SKU and variation SKU search, and optional add-to-cart controls.

Store owners can configure search presets to control which product fields are searched, which details appear in results, and how each search bar looks and behaves. NivoSearch supports product titles, descriptions, SKUs, categories, and tags, depending on the selected settings.

Built for WooCommerce stores of different sizes, NivoSearch combines configurable product search, mobile-friendly layouts, multilingual support, and product discovery tools in one plugin. Its search features help shoppers find relevant products even when they misspell a search term or know a product by its SKU.

Why choose NivoSearch?

NivoSearch improves WooCommerce product discovery by showing relevant product suggestions while customers type. Instead of requiring shoppers to submit a search and wait for a separate results page, it lets them inspect matching products directly in a live search panel.

Key benefits include configurable product search, SKU and variation SKU matching, built-in typo corrections, fuzzy search fallback, and optional add-to-cart controls. Store owners can customize search behavior and presentation for different areas of their store using separate search presets.

The free WordPress.org version supports up to 10 custom typo correction rules. Project documentation refers to a separate Pro tier, which is not included in this plugin download.

Features

• Live WooCommerce Ajax Search: Display matching products as customers type, without a full page reload. Results are ordered by relevance, with product title and SKU matches contributing to ranking.
• Configurable product search: Choose whether to search product titles, full and short descriptions, and SKUs. Category and tag matches can appear in separate result sections when enabled.
• SKU and variation SKU search: Help shoppers find products using product codes. A variation SKU match returns the parent product in the search results.
• Typo correction and fuzzy search: Use a built-in dictionary containing more than 300 common corrections. When a search returns no products, the indexed fuzzy search fallback can suggest close matches. An optional clickable “Did you mean?” suggestion is also available.
• Custom typo correction rules: Add up to 10 custom correction rules in the free version to address store-specific product names and common spelling mistakes.
• Customizable product details: Choose whether search results display product images, prices, SKUs, short descriptions, stock status, category labels, and highlighted search terms.
• Product availability filters: Exclude out-of-stock products or selected product IDs from search results.
• Add to cart from search results: Optionally display an add-to-cart control and quantity selector for eligible products. Variable products link to their product pages so shoppers can choose the required options.
• Unlimited search presets: Create separate search configurations with different search scopes, display settings, colors, dimensions, result counts, and search delays.
• Shortcode and block support: Add a search bar using the [nivo_search id="123"] shortcode or the NivoSearch block in the WordPress block editor.
• Optional theme search replacement: Replace search forms rendered through supported WordPress and WooCommerce hooks or the core Search block. Custom theme markup may require the shortcode or block instead.
• Mobile search overlay: Use a full-screen search interface on narrow screens for a mobile-friendly product discovery experience.
• Recent search history: Store up to eight recent queries in the visitor’s browser, display them when the search input is focused and empty, and allow individual entries or the entire history to be removed.
• Multilingual and accented search: Scope product and taxonomy results to the current WPML or Polylang language and match accented or unaccented words.
• WooCommerce search results page: When enabled, route submitted WordPress searches to the WooCommerce shop page. If that page is unavailable, show product-only search results.
• View all results: Optionally display a link from the live search panel to the full product results page.
• GA4 and Google Tag Manager events: Send search events to an existing GA4 or Google Tag Manager integration. NivoSearch does not load the analytics scripts. See the Privacy and data section for details.
• Search index and caching: Maintain a local product word index for fuzzy matching and cache search results for five minutes. Rebuild the index from the plugin settings when necessary.

Who is NivoSearch for?

NivoSearch is designed for WooCommerce store owners who want to improve product discovery with live search without developing a custom search interface.

This WooCommerce Ajax Search solution can be useful for stores where customers:

• Need to find products quickly without leaving the current page.
• Search for products using SKUs or variation SKUs.
• Frequently misspell product names or search with accented and unaccented words.
• Want to inspect product images, prices, stock status, or other details before opening a product page.
• Prefer to add eligible products to their cart directly from search results.
• Shop on mobile devices and need a responsive search interface.
• Browse multilingual catalogs using WPML or Polylang.
• Need different search configurations for different pages or sections of a store.

Search index and performance

NivoSearch uses standard WordPress queries for regular product searches. A local product word index supports the fuzzy search fallback and can be rebuilt from the plugin settings.

Product saves update the index. After importing products, rebuild the index if indexed terms are missing. Search results are cached for five minutes, and the cache is invalidated when products or presets change.

Actual search response times depend on the store’s hosting environment, database performance, product catalog, and configuration. No fixed response-time or catalog-size guarantee is made.

WooCommerce Ajax Search compared with standard search

The standard WooCommerce search form generally submits a query and loads a separate results page. A WooCommerce Ajax Search interface can display matching product suggestions while customers remain on the current page.

NivoSearch adds configurable live product suggestions, SKU and variation SKU matching, typo correction, fuzzy search fallback, product details, and optional add-to-cart controls. Store owners can choose which product fields are searched and which details appear in the results.

These features give shoppers another way to discover products without replacing the underlying WooCommerce product catalog or requiring a separate search service.

Privacy and data

Search queries are sent to the store’s own WordPress site to retrieve results. Recent searches are stored in the visitor’s browser using localStorage, with up to eight entries. When the typo correction system changes a query, NivoSearch records the original and corrected terms in a local correction analytics table.

The Google Analytics tracking setting is enabled by default. If an existing Google Analytics 4 gtag function or Google Tag Manager dataLayer is present, NivoSearch sends a search event containing the query and result count. NivoSearch does not load those analytics scripts or check consent itself.

Store owners should disable the tracking setting or coordinate it with their site’s consent tool as required by their privacy and consent policy.

When the plugin is deactivated or deleted, presets and settings are preserved by default. Transient caches are removed on deletion. Enable “Delete all data on uninstall” in NivoSearch settings before deleting the plugin if you want it to remove its presets, settings, and custom tables as well.
