Support for mongodb collation feature in data index queries

Currently in data index we only have case sensistive search. MongoDB provides collation to have case insensitive search in queries. Can this be added to all data index persistence. If it cant be added as a input in graphql is there any way to add it to applicaiton.properties to enable. like / eq must support case insensitive search in mongo db persistence. Its just a simple add of collation with strength 1.
