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.*

You can search documents on your Mac using iPhone or iPad. Just Sync your files over WiFi with a single click and move all documents with you anywhere.

Functionality great at first, issues with support

PDF Search worked great for about a week then stopped working. I contacted support via email, never heard back from them. Removed and reinstalled the app and it works again but now it prompts to pay a second time. Does not recognize the Restore Previous Purchase function I have asked Apple for a refund.

UPDATE: I figured out what happened. I had activated the app using the license key from your email. The next time the App Store prompted me to install updates I did and a different (newer?) version of PDF Search installed. That is when it stopped being recognized as PRO. I have removed everything, reinstalled from the link in my purchase email, and reactivated. Everything is working now. This is confusing and, I assume, I should never let the App Store update PDF Search and only do that from Check Updates within the app. Thanks for getting back to me.

Developer Response ,

Hi Olivaaw, Sorry for the bad experience you had. I have checked for your email but somehow it didn’t reach to me. Can you use our support page to contact? I will do my best to help you. For restore purchase problem, is it oossible that you have bought our paid PRO version (with black icon) and then tried to restore it downloading free version? If this is the case please check PDF Search PRO (paid app) to download. For any case I can help you better if you contact through our support page. Regards.

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.

Great Application, but Confusing User Interaction Design

When the application window is opened, I can't use search key combination to evoke search on the menu bar. I cannot use Cmd-W to hide the window, and when pressing Cmd-Q, the whole application closed, causing the menu bar icon disappeared. I'm hoping there could be a better way to evoke PDF search for a quick search.
