One drawback of splitting a source document into multiple pages on wikisource (see T275319#9818815) is that it disrupts Ctrl-F browser search to find a particular bit of a long split document.

However, we can bind Ctrl-F (or /, see this UX discussion for some ideas) to search within "all pages with the same prefix" (or "all pages in the same category" perhaps?). This could potentially be controlled with a {{#searchcontext}} parser function to select the proper category or whatever.

This would also work with T365806: Infinite scroll for articles (split documents on wikisource) to further reinforce the UX feel that a chained set of articles is "all one document".
