Can I search a PDF to find the first time a word appears in a document?

I am a college student, and I use Adobe Acrobat to read pretty much all of my textbooks. When I search the textbooks, it always takes me to the next closest result for that word or phrase. I am often search for the first use of the word in the book so I can get to its definition quickly. This means clicking "previous" multiple times. Sometimes a word isn't mentioned after, so it scans through the hundreds of pages which, to be fair, it does very quickly, but when I am doing this over and over it becomes very obnoxious. So, I typically have to scroll to page 1 and then search,  but that is just as obnoxious. I looked through a few articles and the Acrobat Search help page, but I didn't find any settings that do what I want. Is there a setting I can alter so the search function starts from page 1 rather than my current location in the PDF?

Thanks,

Harrison
