Straighterline - Open Book Searching / Help Please

[allvia]

I've signed up for a few SL course all that are open book for the exam, my question is I cannot figure out the best way to search when taking the Quiz Tests in the e-book that comes along with the course. Help on utilizing the search feature of the e-book (that displays through the bookshelf app) would be greatly appreciated.  Feel free to message me if you have tips but aren't comfortable posting publicly. All required courses for my degree and getting these topics completed as quickly as possible is my goal. 

Currently I'm signed up for:

Business Statistics
Financial Accounting
Managerial Accounting

If these go well I'm considering also signing up for Organizational Behavior, Introduction to Business, Principles of Management, and Business Ethics.
