+
+    Look up the given pillar in a given dictionary and return the result
+
+    :param lookup_dict: A dictionary, keyed by a pillar, containing a value or
+        values relevant to systems matching that pillar. For example, a key
+        could be a pillar for a role and the value could the name of a package
+        on that particular OS.
+
+        The dictionary key can be a globbing pattern. The function will return
+        the corresponding ``lookup_dict`` value where the pillar value matches
+        the  pattern. For example:
+
+        .. code-block:: bash
+
+            # this will render 'got some salt' if ``role`` begins with 'salt'
+            salt '*' pillar.filter_by '{salt*: got some salt, default: salt is not here}' role
+
+    :param pillar: The name of a pillar to match with the system's pillar. For
+        example, the value of the "role" pillar could be used to pull values
+        from the ``lookup_dict`` dictionary.
+
+        The pillar value can be a list. The function will return the
+        ``lookup_dict`` value for a first found item in the list matching
+        one of the ``lookup_dict`` keys.
+
+    :param merge: A dictionary to merge with the results of the pillar
+        selection from ``lookup_dict``. This allows another dictionary to
+        override the values in the ``lookup_dict``.
+
+    :param default: default lookup_dict's key used if the pillar does not exist
+        or if the pillar value has no match on lookup_dict.  If unspecified
+        the value is "default".
+
+    :param base: A lookup_dict key to use for a base dictionary.  The
+        pillar-selected ``lookup_dict`` is merged over this and then finally
+        the ``merge`` dictionary is merged.  This allows common values for
+        each case to be collected in the base and overridden by the pillar
+        selection dictionary and the merge dictionary.  Default is unset.
+
+    CLI Example:
+
+    .. code-block:: bash
+
+        salt '*' pillar.filter_by '{web: Serve it up, db: I query, default: x_x}' role
