In the ebook (available on the website at Downloadable Ebook under Resources), most reader apps will allow you to quickly locate words and phrases in both the text of the novel and the annotations. For the time being, search functionality on the website is limited, but within a given chapter users can easily search for a word or phrase by using the Find function on their web browsers. Here are several options:
On dekstop devices, the browser's Find bar can be quickly accessed by pressing Ctrl+F (Windows, Linux, Chrome OS) or Command+F (⌘F) (MacOS). Type in the desired text, use the forward and back arrows to move to other matches, and tap "x" when finished.
On mobile devices running iOS, Safari allows users to search a
web page by tapping the Share button (square with
arrow), going down to Find on page (magnifying glass
icon), and entering text in the input box. Use the forward and
back arrows to navigate between matches, and tap "Done" when
finished. Chrome reportedly has a similar Find in Page function.
I have not tested this or the many other mobile browser Find
functions that no doubt exist.
Among other uses, a Find function can help readers who, prompted by connections made in a note, want to compare the passage they are presently reading with another passage elsewhere in the novel. By opening a new browser window, loading the appropriate chapter (always identified in the notes), and searching for an identifying word or phrase (also supplied in the notes), they can switch back and forth between passages that illuminate one another.
Readers of the novel can also search for appearances of a word or phrase within a chapter and then find them in a printed text of the novel. To do that, go to the chapter, click on one of the pagination tabs (under Editions on the dekstop website, or Unpaged on the mobile site), and then run the Find function.
Most Find functions are not case-sensitive, so typing "bloom" will pull up all appearances of "Bloom," and vice versa. But they do pay attention to spaces before or after a word, so "bloom" will pull up appearances of "blooming," but "bloom_" will not.
