Hello,
im trying to create ElasticSearch mapping in Symfony 2 with help of
FOSElasticaBundle. Well it probably is not relevant that I use Symfony 2,
but relevant is the fact that Im trying to create mapping as similar to
MySQL schema as I can. I stumbled upon situation, where I have foreign key,
which can be null. As far as I know there are multiple ways to implement
foreign key in ElasticSearch, I chose child/parent approach. Can I
implement in this approach the null foreign key which would mean that type
would have defined parent, but in some cases parent wouldnt exist?

This should be fine.
You can always de-normalize your MySQL scheme in your elasticsearch indexes.

Yes that is an option, but the question was specific - is there a way to
add document to type which does not contain parent, if in mapping there is
parent for that type, like relational DB null reference.
