Searching from home is the same on Oasis2 (same as highlighted and searched). Again it is fuzzy when I look for "he shook his hands" so all kinds of combinations appear if "hands", "shook", and "his" are in close proximity. "He" is (wisely?) ignored, maybe it is too common a word.
By default it will search everything, to look in books you need to select "Text in Books (54)" in my case. The 54 is the number of books it found the phrase in. The list of books then can be sorted by "Number of Hits" "Recent" "Title" and "Author".
I have a PW1 at home I can check later if it does something similiar. Apparently I am not at home right now.
