Searching for individual words will bring up any reference to each word. Quote marks round several words will bring up references to all the words used together (ie "capital accounting"). Using an asterisk will match words starting with the preceding letters (ie acc* will bring up account, accountancy, accounting). Results are shown by chapter and highlighted in the text.
Printing from the PDF will give more control over printing specific A4 pages. Typically printing from the browser will print the entire chapter you are viewing.
