Natural Language Processing
to make Linguistic Search

PDF Search indexes documents considering their unique language attributes. Utilizing Apple's Natural Language framework, it identifies words, plurals, and lemmas. This means that when you search, it considers the semantic meanings of the words, ensuring a more context-aware search experience.

What will NLP do for me?.

Imagine you're searching for the phrase work with mouse across multiple documents. Thanks to its Natural Language Processing capabilities, PDF Search will also identify pages that contain the phrase work with mice, recognizing the plural form of 'mouse'.

There's no need to distribute entire documents spanning hundreds of pages just to share a few pertinent ones. With PDF Search, you can export the most relevant pages from your search results into a new PDF document. This way, you can easily share a concise summary report in a single document with your colleagues.

 
Features

Not only for PDF

PDF Search extends its capabilities beyond PDFs, supporting office documents like Word, PowerPoint, Pages, Keynote, and RTF, as well as text files (TXT, TEXT, ME) and source codes (C, Java, Objective-C, Swift, XML, Python). You can search and view these formats just as quickly as PDFs, and there's no need for native applications to be installed to do so.

These documents must first be converted to PDF in order to be indexed. For this, you can use our auxiliary application, 'PDF Converter'. 'PDF Converter' works integrated with the 'PDF Search' application and converts non-PDF documents to PDF before indexing.

This feature is particularly useful when dealing with thousands of documents. The entire index database and files are copied over, eliminating the need to re-index these documents on your iOS device.

Key Points

What makes it different?

PDF Search conducts searches intelligently. Rather than just verifying the presence of keywords, it analyzes each page individually, assessing its relevance based on the specified keywords. This process is akin to how a human would review documents. For instance, a human would pay more attention to a page if its title contains the keywords. PDF Search integrates all these types of assessments into an innovative artificial intelligence algorithm. Using this approach, it swiftly identifies the most pertinent pages among thousands of documents.
