Searching library databases requires a different approach compared to using Google. Rather than asking a complete question, you should start by selecting just a few keywords based on the main concepts in your research question.
By default, search results show only items for which our library provides full text access. That means you shouldn't come across articles you can't read in full (if you do, just ask a librarian for help). However, you have an option along the left column of the results list to "Expand results to include items without full text," which will increase the number of results retrieved and it will include items for which you would need to make request to borrow from another library.
