You can use the DocumentViewer to preview the PDF and then search for the text using the DocumentViewerFindText object. Here are resources that will help you with this. https://www.leadtools.com/help/sdk/v22/dh/javascript/doxui/documentviewerfindtext.html https://www.leadtools.com/help/sdk/v22/tutorials/html5-get-started-with-the-document-viewer-demo.html
