Description

The Xpdf extension adds full-text indexing of PDF files to the SearchWP engine, extracting content from each PDF attached to the media library so terms searched within the documents appear in search results. Designed for those maintaining technical libraries, manuals, e-books, or PDF catalogs in WordPress, the integration works via the Xpdf binary installed on the server and processes each upload automatically, keeping the index updated without manual intervention.

Main Features of Xpdf Integration

  • PDF text extraction
    Reads the internal content of each PDF file in the media library via the Xpdf binary on the server.
  • Indexing in the SearchWP engine
    Dumps the extracted text into the main search index, along with posts, pages, and products.
  • Automatic processing on upload
    Triggers extraction as soon as a new PDF is uploaded to WordPress, without manual action.
  • Compatible with relevance rules
    PDF content respects weights and filters configured in the SearchWP algorithm.
  • Support for large documents
    Processes multi-page PDFs, preserving the full text for internal querying.

Benefits of Xpdf Integration

  • Search inside documents
    Visitors find terms that exist only in the body of the PDF, not just in the attachment title.
  • Visible technical documentation
    Manuals, datasheets, and e-books stop being isolated from the site’s internal search.
  • No manual transcription
    Eliminates the work of copying PDF content into description fields or metadata.
  • Expanded search coverage
    The index then reflects the entire PDF collection, generating more useful results for users.

Who Is Xpdf Integration For?

  • Those who publish e-books, white papers, or reports in PDF and want the internal text to appear in site searches.
  • Intended for those maintaining libraries of technical documentation (manuals, datasheets, specifications) and need clients to find specific terms within files.
  • Course sites, membership areas, and research portals with PDF support material that require comprehensive search across the entire collection.

How to Download Xpdf Integration

Xpdf Integration is available for download here on Ultrapack. After saving the .zip file, install via the WordPress dashboard under Plugins > Add New > Upload Plugin, select the package, and activate. With SearchWP already active, the extension will automatically index PDFs according to the Xpdf binary configured on the server.

By combining native PDF text extraction with the SearchWP index, the Xpdf extension transforms previously invisible attachments into fully searchable content, without relying on manual copying or external OCR services. It is a straightforward component for sites that treat PDF as an information asset, not just as an isolated download file.
