A properly functioning search system is an important part of every website. Especially when it comes to online stores, magazine blogs, news websites, forums, and directory websites, the search system is a crucial element for providing effective user experience.

For example, if you have an online retail store, you’d want your customers to quickly find the products they’re looking for. And possibly make things easier for them by providing auto-suggestions and product previews in the search.

Unfortunately, WordPress doesn’t provide you the necessary tools to create such a user-friendly search system. Most of the time, you’re left with the default search function that comes with your WordPress theme. And that only helps to a certain extent.

In order to create a more responsive and useful search system, you’ll have to install a third-party WordPress search plugin. Today, we’re taking a look at some of the best options for creating powerful search systems in WordPress.

Let’s see which search plugin is best for your website.

Why Use A WordPress Search Plugin?

The default search system available in WordPress is only capable of searching the title and the content of posts. This can limit the capabilities of your website or store.

If you have an online store, your search system should be able to scan product pages and details to offer better results to customers.

For example, our knowledgebase WordPress theme KnowAll has a custom search engine that offers instant suggestions to searches. So that users can find solutions to problems and articles before they even finish typing the search.

For a knowledge base website, such a feature can drastically improve the user experience. The same can be applied to an online store, a forum, or even a blog or a news website.

At the moment, the only way to integrate a better search system is to use a third-party plugin.

SearchWP vs Relevanssi

When it comes to search plugins, there are many different options you can choose from. However, you only have to worry about choosing between two plugins.

SearchWP and Relevanssi are arguably the two most popular search plugins available on WordPress. One is free and the other is a premium plugin. One is quite difficult to setup and the other is beginner-friendly. Let’s see which is which.



SearchWP is the go-to choice for adding advanced search systems to websites, especially when it comes to eCommerce and business websites.

SearchWP is a premium plugin with a much deeper level of search capabilities. It can even scan and search for content in PDF documents.

Main Features

  • Ability to install and setup the search system without coding
  • A deeper level of search index with support for WooCommerce products, PDF, metadata, and more
  • Get detailed insights on user searches and search terms
  • Integration with WooCommerce, Easy Digital Downloads, bbPress, and more

Benefits Of Using SearchWP

  • Automatic Integration: The plugin automatically integrates with the default WordPress search system. There’s no need to edit code.
  • Multiple Search Forms/Engines: Using SearchWP, you can create and configure different search engines to provide specific types of results
  • Customizable Algorithm: SearchWP search algorithm is highly customizable. You can even choose how search results are ranked.
  • Exclude Results: You can also choose to exclude specific results from searches.

Downsides To Using SearchWP

  • Expensive Pricing: SearchWP has divided the availability of extensions into different pricing plans. Which can be inconvenient to small business websites.
  • Limited Multisite Support: SearchWP doesn’t support global search for multisites. You need to install the plugin individually on each site.

Pricing Plans

SearchWP pricing plans start at $99 per year with standard extensions. The $149 per year plan includes WooCommerce integration, custom results ordering, and metrics. The $299 per year plan lets you install the plugin on unlimited sites with all extensions.



Relevanssi is the biggest competitor to SearchWP plugin, mainly because it includes a generous free plan that pretty much covers all the features of the SearchWP basic plan.

Unlike SearchWP, Relevanssi supports multisites as well as membership plugins. However, it does have a complicated setup process.

Main Features

  • A generous free plan with lots of great features

  • Supports integration with popular membership plugins

Benefits Of Using Relevanssi

  • It’s Free: The biggest benefit to using Relevanssi is that the free plan is more than enough for small blogs and business websites.
  • Search Results Based On Relevance: Relevanssi also shows search results based on relevance to the search terms. Not the publish date.
  • Deeper Indexing: The plugin supports indexing of almost all types of content, including PDF, documents, ePub, shortcode content, and more.
  • Plugin Integration: Relevanssi supports integration with various plugins such as WPML, a2Member, WooCommerce, and more.

Downsides To Using Relevanssi

  • Advanced Setup Process: The settings page of the plugin is quite difficult to understand at first glance. And requires a bit of technical knowledge to fully setup the plugin.
  • Heavy Resource Usage: The plugin page has a warning that mentions heavy database space usages in hundreds of megabytes.
  • Plugin Conflicts: Relevanssi doesn’t work well with many third-party plugins such as BuddyPress, BeaverBuilder, NextGen Gallery, and Sensei

Pricing Plans

In order to access the more advanced features like the ability to index PDF documents, multisite support, and more you’ll need the premium version of the plugin. It costs $99 per year or a one-time price of $349 for a lifetime license.
