SearchWP Xpdf Integration
SearchWP offers the unique feature of extracting plain text from PDF files uploaded to your WordPress website. Out of the box, SearchWP attempts to do this using only PHP, but due to the complexity and variation of the PDF format, sometimes content is not extracted accurately.
By using the Xpdf integration extension, you can offload all the work that PHP has to do to process your PDF files to Xpdf's command line tools, which are extremely fast and accurate when extracting content from your PDF files. After activating the extension, you will need to follow the installation instructions. Once SearchWP Xpdf Integration is installed, SearchWP will offload the PDF content extraction process to Xpdf.
