The vast majority of searchers don't use quoted searches. About the only ones I know of who do are SEOs and webmasters who are checking up on their rankings for quoted searches, and maybe a handful of professional researchers.
The average searcher likely doesn't even know the option exists, and even if they do, they very rarely use it.
So unless your site visitors are very unusual people (or professional researchers), I wouldn't expect high rankings on a quoted search to make a huge difference in your actual traffic.
That said, to improve your ranking for a quoted search, you need to make sure you optimize the page for the exact words
within the quote marks in that exact order
with no other words in between
Don't optimize for science books
or science and history books
or scientific book
if you want to rank for the exact phrase "science book".
Use the exact phrase in your page title tag and in the on-page text and in the anchor text of links pointing to the page. Then just be patient; give the search engines time to ponder the changes you've made, and see what happens.
