You want to search for a title containing matching parentheses? If so, then this:

title:"~\\(.*\\)"

For why you need two backslashes, see The search interface:

Note that backslashes used to escape special characters in regular expressions must be doubled because single backslashes will be removed during query parsing. For example, to match a literal parenthesis you must enter \\(. Regular expression searches are ‘contains’ searches unless the expression contains anchors.
