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.

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.

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.

PDF Search app has built-in OCR capability. It can index and search texts on images inside documents for the supported languages.*

Useful app

I’ve got literally tens of thousands of documents that I need to search. PDF search does a credible job of searching considering the very low price and the modest features (e.g., no boolean search features). I definitely recommned it. When I need an absolute top quality search of tens of thousands of documents I still use DT search. But compare the price.

Best of Application Type

Having used PDFSearch for several months now, I am significantly empowered by it's ability to quickly locate content that I have read as well have not yet read.

Given about 30,000 documents of which 7,500 or so are books, I can quickly locate research topics in books wherein I would never find this information manually, thus extending my research capabilites simply due to this profound access and retrieval app. Choose a keyword and every book or document you have wil be presented to you in a beuatiful graphical format with the referenced page visible in the adjacent window. Further, the developer, Muharrem, is very thoughtful and helpful and provides personal support when needed.

I highly recommend this app to anyone who is a student, a reporter, a researcher or writer, a teacher of professor that needs to pull information together quickly to present a lecture for example, or someone with a great deal of information they have carefully saved on their computer over the years. Apple Spotlight pales in comparison.

Quite helpful search tool

I very much appreciate PDF Search (currently using Version 1.7). I have thousands of PDFs on my computer, with quite a few folders holding the bulk of them. Years ago I gave up on the idea of tags; I saved PDFs faster than I could decide on what tags to use! Instead I depend on searches. What makes PDF Search so handy is its display of the documents located and their ranking, the display showing the first page of each document and, when selected, the document itself with search terms highlighted. Quite often that first page display alone jogs my memory of the circumstances that led me to collect it in the first place. The indexing process itself takes some time for folders with hundreds of PDFs of course, but that’s hardly a problem because it’s happening in the background. This is a good tool to have on hand.
