Why Should You Enable PDF Search in WordPress?
Allowing WordPress to search PDF files enables visitors to access information contained within uploaded documents such as user manuals, brochures, eBooks, and help guides.
While WordPress allows you to upload and showcase PDFs on your site, its default search functionality only scans the file title and description.Itdoes not analyze the content within the PDF itself.
This can lead to important information being overlooked in search results, even if it is already available on your site. Users might have to open multiple files just to find a single answer.
By enabling PDF indexing, WordPress can incorporate PDF content into search results, allowing users to quickly locate the information they need.
Now, let’s explore how to implement PDF indexing and searching in WordPress. Here’s a breakdown of what we will cover in this guide:
- Step 1: Install and Configure SearchWP
- Step 2: Tailor Your WordPress PDF Search Settings
- Step 3: Create and Integrate a Custom Search Form (Optional)
- Bonus Tip: Optimize Your Use of SearchWP to Enhance WordPress Search Functionality

Step 1: Install and Configure SearchWP
The most effective way to enable PDF indexing and searching in WordPress is by utilizing SearchWP. This powerful WordPress search plugin allows you to include various content types in your search results, such as custom post types, WooCommerce products, comments, PDFs, and more.
For more information, check out our comprehensive SearchWP review.
To begin, create a SearchWP account by visiting the SearchWP website. Click on ‘Get SearchWP Now,’ select a plan that suits your requirements, and complete the registration process.
💡Please Note:In this tutorial, we will utilize SearchWP Pro, which provides comprehensive control over indexing, including PDF files. Additionally, there is a free option called SearchWP Live Ajax Search that enhances your website’s search functionality with real-time results as users type.
Once your account is created, you’ll access your own SearchWP dashboard. Here, download the plugin zip file and copy your license key, as you will need both for the upcoming steps.
Next, let’s proceed to install and activate SearchWP on your WordPress site. From your admin dashboard, navigate to Plugins » Add New Plugin.
On the following screen, click the ‘Upload Plugin’ button.
Then, select the SearchWP zip file you downloaded, click ‘Install Now,’ and wait for the installation process to complete. Once finished, click ‘Activate’ to enable the plugin.
For further information, refer to our detailed guide on how to install a WordPress plugin.
After activation, navigate to SearchWP » Settings and click on the ‘General’ tab.
To proceed, enter your license key in the ‘License Key’ field. You can find this information in your account on the SearchWP website.
After entering the key, be sure to click the ‘Verify Key’ button.
Step 2: Tailor Your WordPress PDF Search Algorithm
Now you’re set to integrate the content of your PDF files into the WordPress search results.
To begin, navigate to SearchWP »Algorithm.
This will take you to a page where you can define what content SearchWP should include in its search results, such as pages and posts.
By default, SearchWP is configured to search your site’s media files. If you don’t see a ‘Media’ section, you’ll need to add it by clicking the ‘Sources & Settings’ button.
This section displays all the various types of content that can be included in the WordPress search results. For instance, you can enable search functionality for blog comments in WordPress.
In the popup window, select ‘Media’ and then click ‘Done.’
To enable the search engine to index PDF files in WordPress, scroll down to the ‘Media’ section.
Here, click the ‘Add/Remove Attributes’ button.
In the popup that appears, ensure the ‘Document Content’ box is checked if it isn’t already.
These settings instruct SearchWP to index the content of your PDFs, Microsoft Office files, text documents, and other files stored in the WordPress media library. This content will be included in relevant search results.
Make sure to select the ‘PDF Metadata’ option. This allows SearchWP to index metadata from PDFs that is not part of the document’s content, including the title, author, subject, and keywords.
Depending on the specific PDF, this feature can assist visitors in locating the information they need.
For instance, if you operate an online store, including metadata can help customers find the PDF user manual for a particular WooCommerce product. Therefore, it’s often beneficial to display this information in search results.
Once you are satisfied with the adjustments you have made, click the ‘Done’ button.
The ‘Document Content’ and ‘PDF Metadata’ options will now be visible in the ‘Media’ section, along with other default attributes that SearchWP searches, such as title and slug.
You will see that each item has an ‘Applicable Attribute Relevance’ scale, which indicates the importance that SearchWP assigns to each attribute.
Content that closely matches a search attribute will rank higher in search results, while content with less relevance will appear lower.
By default, the sliders for Document Contents and PDF Metadata are set to a low value, limiting their influence on search results.
To ensure WordPress indexes and searches PDF files effectively, adjust these sliders to enhance their significance. This instructs WordPress to prioritize the content within your PDF files in the custom search results.
Every WordPress site is distinct, so experimenting with different relevancy settings can help you achieve the most accurate and useful search results.
For instance, if you’ve uploaded your restaurant’s menu as a PDF, it’s crucial content that should typically rank high in search results.
Once you’re satisfied with the search configuration, scroll to the top of the page and click the ‘Save’ button.
SearchWP will automatically rebuild the index.
The time this takes may vary depending on your Internet connection speed and your WordPress hosting provider, potentially taking a few minutes.
Once you see ‘Index Status 100%,’ it means that SearchWP has successfully included all PDF content and metadata in its search index.
Well done!
Your WordPress website or online store will now display PDF content and metadata in its search results.
Step 3: Create and Embed a Custom Search Form (Optional)
While completing steps 1 and 2 is sufficient to make PDF files searchable in WordPress, we recommend creating a custom search form to enhance the search experience further.
This allows you to design a search bar that aligns better with your users’ search habits. If your site has extensive content, your visitors may prefer a search bar with menus to refine their results.

In this section, you can enable the following options:
