Case insensitve index in Titan ("exact" match)

[okram]

Certain fields want to retain the original String provided by the client, but still be able to search on any cased permutation of that String. However, they don't want the expense of ElasticSearch when this can probably be easily provided by Titan exact match where the indexing is into a toLowerCase() representation of the String.

gremlin> g.addVertex('email','MarkoRodriguez@spam.com')
==>v[0]
gremlin> g.V().has('email','MarkoRodriguez@spam.com')
==>v[0]
gremlin> g.V().has('email','markorodriguez@spam.com')
gremlin>

Wait a second... this is a bad idea for Gremlin though.

gremlin> g.V().out('knows').has('email','markorodriguez@spam.com') // not what you expect
gremlin>
