Search is a feature in the Olive Tree app that will help you find a Bible verse or a word in a book you have downloaded to your Library. Here's a tutorial about the basics of how to search in the app.
To start a search, select the search box in the upper right corner of the app.
Type your search term and then hit enter. All of your resources will be searched at once and you'll be able to see how many times your search term appears in each resource.
Click on a resource to see all the results for that word in that resource.
