Users can easily search the eighteen chapters of Ulysses on this site by using the Find function on their web browsers. Methods of display vary from app to app, and methods of accessing the Find bar vary from OS to OS. Here are some commonly used options:
For full-sized computers with keyboards, the browser's Find bar can be quickly accessed by pressing Ctrl+F (Microsoft Windows, Linux, or Chrome OS) or Command+F (⌘F) (Apple OSX). Type in the desired word or phrase, use the arrows in the bar (if present) to move to later or prior matches, and close the bar ("x") when finished.
On iPads and iPhones, Safari allows users to type in the desired word or phrase in the URL bar, scroll past the "Google Search" suggestions down to "On This Page," and tap "Find (word or phrase)." Use the arrows at the bottom of the screen to move to later or prior matches, and tap "Done" when finished.
I do not use an Android phone or tablet so I have not checked this feature, but Chrome for Android, like Safari for iOS, reportedly has a "Find in Page" function. Type a word or phrase into the URL bar, look at the scroll-down list, and click on the icon that has a magnifying glass inside a square box. Use the arrows to move between matches, and tap "x" when finished.
Among other uses, these Find functions will serve readers who want to heed the suggestions of the notes and 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 may also want to 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 "Apply pagination" tabs under "Editions" (on the full-size website) or the "Unpaged" tab (on the mobile website), 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.
