How to not lost hasMany changes on Ember query?

In my application, I search for documents with query. Then I edit one attribute in a single document, and then I call search query again. Result is OK, I see document still in a dirty state with changed attribute.

Then I again pick one of documents and edit its hasMany relation (from 2 items to 4 items). And then I call search query again. Result is NOT OK, hasMany relation change is lost/disposed/rollbacked.

Is there a way so Ember query (i guess it's some Ember internal reload) does not rollback not saved relation changes ?

I use ember 2.9.1

For now i have no other way than prohibit any filter query actions or route actions anything that could call query again, since that would cause lost data that user set.
