Searching
Loggerhead's /search page is backed by the bzr-search Breezy
plugin. You need to have the plugin installed in the Python environment
that Loggerhead is calling into, and each branch must be indexed before
its contents become searchable.
Indexing a branch is a Breezy-side operation:
brz index /path/to/branch
If the plugin isn't available or the branch hasn't been indexed, the
/search page renders a "search unavailable" notice rather than
erroring out.
