The MongoDB version is 2.6.10 on an Ubuntu 16.04.4 LTS. To import the data I
didn't take any special steps. From what I could gather the problem is that the
`ports` property is very complex and that may be the origin of the problem.

We haven't had the time to look at this. We'll try to do a repro.
Can you share the details of the MongoDB version that you're using and whether
there are any specific steps to load the data?

Did you try enclosing the word with accent quotes?
{code:sql}
select `ports` from mongo.ivre.hosts;
{code}
