You probably have ever labored on a WordPress website with an enormous quantity of posts and pages, you will have spotted one thing concerning the WordPress seek: it doesn’t carry out neatly. On this article, we dive into why the default WordPress seek doesn’t scale and a few techniques to make it higher.

How WordPress Searches

By means of default, the local WordPress seek plays a question for your database that appears one thing like this:

Let’s destroy down this question just a little bit.

  • First, we’re the use of SQL_CALC_FOUND_ROWS at the wp_posts desk. This says, if there have been no restrict (coming later), how many results would the next question flip up?
  • Then we seek throughout the post_title, post_excerpt, and post_content columns for the hunt time period (on this instance I searched “tech”).
  • And we make certain that the content material returned is a put up, web page, or attachment (media).
  • We test to ensure the standing is “public”–no longer deleted or personal (in case you are a logged-in consumer it’s going to additionally seek best your personal personal posts).
  • We order the effects via matching name, descending, or put up date, descending.
  • Final, we restrict the effects to ten, paginating the remainder of the effects.

That’s quite a lot of assessments WordPress runs thru simply to go back seek effects. And each and every time you iterate thru wp_posts to accomplish every test, MySQL is processing all rows in wp_posts. If you have loads of hundreds of rows within the wp_posts desk, this question can get unsightly in point of fact fast. Listed below are some benchmarks from a couple of of my websites:

On websites with an excessively massive collection of posts, the question took over 20 seconds! This isn’t a scalable seek possibility for websites with prime site visitors.

Downside Id

Figuring out what we now know concerning the default seek conduct, it’s essential to name out why this may not be superb for some web sites.

  • WordPress best searches the “post_title,” “post_content,” and “post_excerpt” fields to your seek phrases. It additionally best gifts “put up,” “web page,” and “attachment” put up varieties. For customers with customized put up varieties, customized fields, or plugins like WooCommerce that upload other web page/put up varieties, this can also be problematic: these things is not going to seem in seek effects.
  • The question utilized by WordPress seek plays very poorly at over 100,000 posts. For information websites or media websites with greater than 100,000 posts, a seek may just take a number of seconds to accomplish.
  • The deficient efficiency at the seek question may just motive server efficiency problems in case your website receives a good quantity of seek site visitors.
