+% SEARCH selects AOs that match the given name.
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% DESCRIPTION: SEARCH selects AOs that match the given name using a regular
+%              expression (help regexp).
+%
+% CALL:        b = search(a, 'foo')  % get all AOs from <a> called 'foo'
+%              b = search(a, 'foo*') % get all AOs from <a> with a name like 'foo'
+%              b = search(a, pl)
+%
+%
+% This function returns the handles of the AOs that match the regular
+% expression. No object copying is done.
