Question:Is there an easy way to find specific text within a paragraph?I'm having trouble with a big PDF file. I have all the answers I need in it to pass, but it is all randomly placed information. Like in one paragraph, it talks about farming, then the next about Communism. But what I need to find is only some things. What I'm saying, is there an application that you can choose what text you want to be analyzed for a specific keyword, and then it will tell you where its at?
Answer: One solution is that “Hit Ctrl+F or look for the "Find" button, enter the word you're looking for and it'll jump through every point in the doc that the word comes up.” This solution works only when the PDF is text based. When handling image based PDF, searching content by this method is not reachable. In the following part, I will show you how to convert image based PDF to text based PDF file.
