of the form
 +/rpc/?v=5&type=search&by=_field_&arg=_keywords_+ where _keywords_ is the
 search argument and _field_ is one of the following values:
 
-* `name` (search by package name only)
-* `name-desc` (search by package name and description)
+* `name` (search by package name or packages which provide that name)
+* `name-desc` (the same as `name` and search by description)
 * `maintainer` (search by package maintainer)
 
 The _by_ parameter can be skipped and defaults to `name-desc`.
