+Search and multimatch handling
+
+This module allows for overloading two functions used by Evennia's
+search functionality:
+
+    at_search_result:
+        This is called whenever a result is returned from an object
+        search (a common operation in commands).  It should (together
+        with at_multimatch_input below) define some way to present and
+        differentiate between multiple matches (by default these are
+        presented as 1-ball, 2-ball etc)
+    at_multimatch_input:
+        This is called with a search term and should be able to
+        identify if the user wants to separate a multimatch-result
+        (such as that from a previous search). By default, this
+        function understands input on the form 1-ball, 2-ball etc as
+        indicating that the 1st or 2nd match for "ball" should be
+        used.
+
+This module is not called by default, to use it, add the following
+line to your settings file:
+
+    SEARCH_AT_RESULT = "server.conf.at_search.at_search_result"
+
+"""
+
+
+def at_search_result(matches, caller, query="", quiet=False, **kwargs):
+    """
+    This is a generic hook for handling all processing of a search
+    result, including error reporting.
+
+    Args:
+        matches (list): This is a list of 0, 1 or more typeclass instances,
+            the matched result of the search. If 0, a nomatch error should
+            be echoed, and if >1, multimatch errors should be given. Only
+            if a single match should the result pass through.
+        caller (Object): The object performing the search and/or which should
+        receive error messages.
+    query (str, optional): The search query used to produce `matches`.
+        quiet (bool, optional): If `True`, no messages will be echoed to caller
+            on errors.
+
+    Keyword Args:
+        nofound_string (str): Replacement string to echo on a notfound error.
+        multimatch_string (str): Replacement string to echo on a multimatch error.
+
+    Returns:
+        processed_result (Object or None): This is always a single result
+            or `None`. If `None`, any error reporting/handling should
+            already have happened.
