Mongodb invalid operator: $eq (version 3.0.6)

In version 3.0.6 of Mongodb (client & server) when I use the operator "$eq" an error appears. Here is an example with the mongo shell:

> version()
3.0.6
> db.doc.insert({tags: [ "A", "B", "C" ] })
WriteResult({ "nInserted" : 1 })
> db.doc.find({tags : {$eq:"A"}})
Error: error: { "$err" : "invalid operator: $eq", "code" : 10068 }

What should I do ?

Thanks for helping

Your code is correct. Try:

db.doc.find({tags: "A"})

It is an equivalent way of writing an equality.
