App Description

PDF Search is an app to search multiple documents insanely fast. It enables you to find any information in seconds within lots of documents. It uses AI-powered search algorithm to detect the best related pages. It has lots of unique features, like NLP based Linguistic Search, Text Recognition (Built-in OCR), Search Results Export, Table of Contents search, which will boost the productivity of your any document based workflows.

WHAT MAKES IT DIFFERENT
Ordinary search tools search for existence. They only check whether your keywords exist in documents or not. Then they give you a bunch of document list. You check them one by one to understand whether they are the one you are looking for or not. There is no intelligence, just like a machine.

PDF Search makes intelligent search. Instead of checking the only existence, 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 this algorithm, it finds the most relevant pages instantly among thousands of documents.

NATURAL LANGUAGE PROCESSING *
PDF Search supports tokenizing and lemmatization while indexing. With this feature you will be able to search plurals or lemma of the keywords. For example when you search for "hike" you will get results for "hiking" also. Or when you search for "children" you will get results for "child" also.

TEXT RECOGNITION ON IMAGES INSIDE DOCUMENTS (OCR)
PDF Search app has built-in OCR capability. It can index and search texts on images inside documents for the supported languages.*
