You can do that by adding the following in your MetaMapper object

override def dbIndexes=UniqueIndex(<name-of-the-field>)::super.dbIndexes

comma separated list of fields can also be provided

for example - UniqueIndex(name,dob)

perhaps `super.dbIndexs` should instead be `super.dbIndexes`? – Shafique Jamal Sep 28 '14 at 01:29
