+Grouped backends
+================
-When possible, commands taking a candidate as an argument are dispatched to
-the back-end it came from. In other cases, the first non-nil value among
-all the back-ends is returned.
+An element of `company-backends' can also be a list of backends. The
+completions from backends in such groups are merged, but only from those
+backends which return the same `prefix'.
-The latter is the case for the `prefix' command. But if the group contains
-the keyword `:with', the back-ends after it are ignored for this command.
+If a backend command takes a candidate as an argument (e.g. `meta'), the
+call is dispatched to the backend the candidate came from. In other
+cases (except for `duplicates' and `sorted'), the first non-nil value among
+all the backends is returned.
-The completions from back-ends in a group are merged (but only from those
-that return the same `prefix').
+The group can also contain keywords. Currently, `:with' and `:sorted'
+keywords are defined. If the group contains keyword `:with', the backends
+listed after this keyword are ignored for the purpose of the `prefix'
+command. If the group contains keyword `:sorted', the final list of
+candidates is not sorted after concatenation.
