Mostly search tools perform existency search according to your given keywords. They only check whether your desire keywords exist in documents or not. Then they give you a bunch of document list. You check them one by one whether they are the one you are looking for or not. There is no intelligence, just like a machine.
PDF Search is and AI-powered search within PDF documents app for iOS. It makes relevancy search. Instead of checking the only existency, It analyses all pages separately and makes a relevancy check for each of them according to given keywords. This check is similar to how a human checks documents. For example, a human is more interested in a page if it has a title containing keywords. PDF Search combines all these kind of checks into a brand new algorithm. Using its AI-powered algorithm, it finds the most relevant pages instantly among thousands of documents.
