+Searching
+---------
+
+To search for a string ``"excellent idea"`` in all journal entries, use the ``-search`` argument::
+
+    jrnl -search "excellent idea"
+
+The ``-search`` argument can be combined with other filters, such as ``-from`` and ``-until``.
+
+Note that the searching is case-insensitive and doesn't accept any wildcards or regular expression syntax.
