## What is Pdf Text Search?

Pdf Text Search is an app to search for text in a pdf document.  Select a pdf document to import, and the app reads the text in that document and converts it into searchable text entries.  As you input your search, the app finds the entries that include your search.  You can search for only the exact text you enter, for one or more words you enter (in any order).  You can also train an artificial intelligence model to identify similar text in a document.  After conducting a search, you can click on the relevant entry and see full text for that entry and click that text to see the pdf page where that entry is located.  You can also save and share entries.  When you import a document, the app saves that document.  You can view saved documents in a list or in augmented reality.

You to select two or more pdf documents and the app will use an algorith referred to as TF-IDF (term frequency - inverse document frequency) to identify terms based on their frequency in the document compared to their frequency in the other selected documents.  After the app has processed your selected documents, you can click on a document to view the top terms based on their TF-IDF score and then you can click on one of those terms, load the document and search for the selected term in that document.
