how to search by SKU in WooCommerce

Are you wondering how to search by SKU in WooCommerce?

Searching by SKU makes it easier for your customers to find the product they’re looking for.

In this article, we’ll show you how to make WordPress search for WooCommerce product SKUs in a few steps.

Why Search By SKU in WooCommerce

To begin with, let’s recall what the SKU is and what it is used for.

SKU is an abbreviation for Stock Keeping Unit. This is a unique product identifier that you can set and use to track the movement of your inventory.

But, in the case of WooCommerce, it can also be used to provide more relevant search results.

For example, let’s say your customers know the exact SKU of a product they’re looking for.

Why not let them immediately find it by entering the SKU into the search field?

It’s a great idea, except for one thing. WooCommerce stores products and SKUs as custom post types and custom fields, respectively.

By default, WordPress completely ignores custom post types and fields while searching.

So using the native WordPress search engine, your customers won’t find any products even by their titles, not to mention SKUs.

Thankfully, there is a way to make WordPress consider custom post types and custom fields while performing a search.

Let’s take a look at it.

How to Search By SKU in WooCommerce

The easiest way to make WordPress search by WooCommerce products SKU is to use a plugin like SearchWP.

When the download is finished, simply install and activate it the same way as SearchWP.

Step 3: Add Custom Post Types as a Search Source

Once you activate the WooCommerce integration extension, the next step is to add custom post types as a search source.

To do so, go over to the Engines tab.

Here you’ll find the list of search engines you currently have.

list of your search engines

Right now, there is only one, the Default search engine which is used for native WordPress searches.

It means that by customizing its settings, you can control how the search works throughout your entire site.

For example, you can indicate what search sources you want WordPress to consider performing a search, adjust the weight of attribute relevance, and many more.

Apart from that, SearchWP allows you to add multiple search engines with individual settings and link them to different search fields.

Now, to make WordPress search by WooCommerce products SKUs, we first need to add custom posts types as a search source to the Default engine.

To do so, click Sources & Settings at the top right.

click sources and settings

Tick the box next to the Products source and press Done.

select products and press done

After that, there will appear the Products search source. As you can see, now it only indexes the title, content, slug, and excerpt of products.

To make it index SKUs, we need to add them as an attribute to the Products search source.

Step 4: Add SKUs as an Attribute

To do so, click the Add/Remove Attributes button.

click add remove attributes

Then, type SKU into the Custom Fields field and choose the _sku option from the drop-down menu.

choose the sku attribute

When you’re finished, click Done.

press done to add a new attribute

As you can see, our newly added _sku attribute currently has the lowest relevance weight.

the sku attribute weight is on the min

It means that WordPress will give it the lowest priority when searching. Since we don’t want that to be the case, let’s set its weight to the maximum.

To do so, move the slider next to the _sku attribute all the way right.

set the sku attribute weight to the max

Once done, press the Save Engines button at the top right to save the changes you made.

press save engines

That’s it. Now your site visitors can find products by their SKUs. Let’s test our new WordPress search to make sure everything works fine.

Step 5: Test Your New Search

For the purposes of this tutorial, we’ve added the “Blue Hoodie” product that has the “BH7564” SKU.

Let’s see if WordPress can find this product solely by SKU.

To do so, we’ll enter the “BH7564” query into the search field on our test site and press Search.
