I am currently building a small search engine, in which the user types in a couple of keywords. I have a set of PDF files, which I first convert to text. Then I search through the text to see which documents have any one of the keywords in them.
My goal is to highlight the keywords in the documents when I display them to the user. I am using DeJango, and for text highlighting plan to use PDFTK.
Hence I was wondering, does anyone know how one can highlighting text in a PDF document using PDFTK? Or any other software tool for that matter?
Thank You!
