Your query JSON object contains name field two times, and it breaks the query. Pay attention to the $and mongo query operator. There are two ways to construct correct query:

1) db.users.find({ $and: [{ name: { $nin: [current_user] } }, { name: { $regex: new RegExp(/query/) } }] })

2) db.users.find({ name: { $nin: [current_user], $regex: new RegExp(/query/) } })

Also, if you exclude only one user, you can use $ne operator instead of $nin.
