The output follows the format of <file_id> <fragment_id> <entity_id> <fully_qualified_name>. To find exact matches on the name, specify the --exact parameter. Note that an entity's name and its fully qualified name are different. For example, searching for logican_and with --exact will return std::__1::logical_and, as shown below:

% mx-find-symbol --db /tmp/xnu.db --name logical_and --exact
1152921504606848236 2305843009214811857 9243638307874668544 std::__1::logical_and CXX_RECORD

In the above, there are two such named entities: the class template, and its "pattern" class (the CXX_RECORD).
