8 Best WordPress Search Filter Plugins Compared

Have you created an online store or an interesting blog? Do you have a lot of posts on your site, so it takes a long time to find something meaningful?

Then you need a filter plugin that will help users find the most important among hundreds of positions on your site. The faster a person sees the right product or information, the better their user experience. So, it is more likely that they will return.

WordPress has a built-in keyword search feature. But often, this is not enough. For example, you sell clothes. Sometimes searching for “women’s pants” isn’t enough to find women’s blue high-waisted jeans. The filter and search system simplify the task and speed up the search.

Today there are hundreds of WordPress filter plugins. I will analyze a few of the most popular ones.

How does WordPress site search work?

Site search works on one similar principle—you enter some search query, the system checks the content on the site, and displays the results in the form of a list. It could be a list in chronological order, in order of relevance, and so on.

How to add a search bar and filters to the site?

For this, WordPress has a built-in functionality. For example, you can select “Search” from the building blocks. But such a search has limited functions. Choose a plugin if you need more options for searching the site and creating filters.

What is a WordPress search filter plugin?

These plugins help you filter the content on your site and quickly find what you need. They significantly affect the comfort of users in communicating with your site. For example, imagine you want to buy the book “55 Biscuit Recipes,” and there is no filter or search bar on the book site. You will have to go through all 180 pages of the website to find the right book. What is the probability that you end up buying it?
