Hi,

I am most likely missing something trivial, but I don't understand what should I do to update an entry in a DB.

I have found two possible methods - update and findAndModify and can't make any of them work. In the mongodb docs there is an example: 

db.runCommand(
                {
                  findAndModify: "people",
                  query: { name: "Tom", state: "active", rating: { $gt: 10 } },
                  sort: { rating: 1 },
                  update: { $inc: { score: 1 } }
                }
             )

those two functions take query and update parameters. The query part is easy, but I don't know how to translate this code: `{ $inc: { score: 1 } }` into the D code.

Can you give me a hint?

Thanks,
Drasha
