Question about UNIQUE KEY for "fields" table

Martin,
as pointed out on the Security Onion mailing list 
https://groups.google.com/forum/#!topic/security-onion/6nXu_vDWI4U I was asking 
myself if this documentation is correct: 
https://code.google.com/p/enterprise-log-search-and-archive/wiki/Documentation#A
dding_Parsers

Given that the "fields" table has "UNIQUE KEY `field` (`field`,`field_type`)", 
it might happen that the query below fails because the inner subquery returns 
more than one result:

INSERT INTO fields_classes_map (class_id, field_id, field_order) VALUES 
((SELECT id FROM classes WHERE class="NEWCLASS"), (SELECT id FROM fields WHERE 
field="dstip"), 7);

Don't you think it would be better to change the UNIQUE KEY to "field" only, or 
changing the documentation in order to use both "field" and "field_type" in the 
WHERE clause (like below)?

INSERT INTO fields_classes_map (class_id, field_id, field_order) VALUES 
((SELECT id FROM classes WHERE class="NEWCLASS"), (SELECT id FROM fields WHERE 
field="dstip" AND field_type="int"), 7);
