RDoc publishes a site's whole search index as one static JS file, the
same way Sphinx and the Node.js docs do, so 'oc ruby search' fetches
docs.ruby-lang.org's index (en/3.4, where the file exists), caches it
under the shared day cache, and ranks it with the same scorer the Node
backend uses. Class methods print as Class.name(params), instance
methods as Class#name(params), and every entry links straight to its
method anchor. 'oc ruby class Array' opens a class page directly.
cli.js now dispatches the local search backends through one map, and
the site-resolution guard keys on the query field, which only a search
shape ever carries.
