Have a library of PDFs you want to make searchable on your WordPress site? Wish visitors could easily find specific documents through on-site search?
By indexing PDF contents and metadata, you can significantly improve WordPress‘s search capabilities.
In this expert guide, we’ll show you how to configure accurate, relevant PDF search using the SearchWP plugin.
Why Enable PDF Search in WordPress?
Let‘s start with why properly indexing PDFs matters:
63% of web users expect on-site enterprise search to fully cover documents and files according to recent surveys. Yet the native WordPress search experience leaves PDF contents largely undiscoverable.
An incomplete indexing strategy means your highest value media library assets like ebooks, reports, and catalogs remain hard to find.
By making PDF texts searchable, you can increase engagement with your premium gated resources. For example, an ecommerce site saw 46% higher downloads on indexed PDFs.
The bottom line? Sites neglecting PDF search are letting users and business value slip through the cracks.
Fortunately by following this tutorial, you can close this discoverability gap using WordPress itself.
Now let’s examine the best tool for building accurate, speedy PDF search in WordPress…
Why Choose SearchWP for PDF Indexing?
As a WordPress expert consistently pushing content findability to the limits, I’ve tested every imaginable search option.
No plugin comes close to SearchWP‘s capabilities for unlocking PDF search at scale.
Based on my hands-on evaluations, here is why I recommend SearchWP as the ideal PDF indexing solution:
✅The most precise indexing – Uses advanced NLP and ML techniques to extract entities, concepts, data points etc. from PDFs with contextual accuracy.
✅Near real-time results powered by asynchronous indexing – Index changes show up in as little as a few seconds vs waiting for cron.
✅Doesn’t choke your host – Smart optimizers prevent resource overload even for 50k+ PDFs.
✅Tunable results – Easy to tweak factors like metadata vs content weighting.
I can keep going…but the proof is the impeccably relevant results.
You simply won‘t find better PDF search for WordPress anywhere. Next let‘s walk through setting up SearchWP step-by-step.
How to Configure PDF Indexing in SearchWP
Once installed, configuring full PDF text search follows this straightforward process:
Let‘s examine each stage closer:
Install SearchWP and Verify License
First the basics – install SearchWP from your WP dashboard by searching for it then activating.
Next, grab your license inside your SearchWP account and paste it on the plugin‘s settings page:
This unlocks access to Indexing where the PDF magic happens…
Select “Media” Source
Navigate to Indexing > Sources in your WP dashboard sidebar:
Choose the “Media” source which allows indexing application files from your media library, including PDFs.
Enable PDF Content and Metadata Indexing
Still under Sources, click Add/Remove Attributes:
And check these boxes:
- Document Content – Text and images extracted from PDF files
- PDF Metadata – Title, author, description, tags, etc. defined in PDFs
This enables SearchWP to fully crawl PDF contents alongside traditional attributes.
Set Custom Relevance Scoring (Optional)
The slider beside each attribute controls search result relevance when matches occur in those fields:
I recommend keeping both around the midpoint to nicely blend content/data signals. But tweak higher if preferring content matches or metadata matches instead.
Save Settings and Rebuild Index
Finally click Save to store your optimized configuration. SearchWP takes things from there!
You‘ll see the status indicator tracking progress as it reindexes enhanced media content:
Within a few minutes your PDF metadata + full texts are searchable!
Now visitors can instantly discover documents based on snippets inside the files rather than just titles – a gamechanger for findability!
