create unique node #7

How do we create unique node? and I also want unique index on some of my node property. (eg. If my node is a type of user, then it should be unique username, email and mobileno.)

thanks

I'm sorry I never responded to this, @sapkal-manish!

To create a unique node, the best way with Neo4j 2.0 is to use a uniqueness constraint on a label. This template app hasn't been updated to use those features yet, but it will soon: issue #11.

Pre-Neo4j 2.0, you can simply do an index lookup before creating the user.

Hope that helps, and sorry again for the delay!
