Hi guys!  
I have company as a parent document and its relation status with other company (a child document with parent id as companyId):  
`company: {companyId, name, address, ...}`  
`relation: {myCompanyId, otherCompanyId, status}`  
I am goint to find companies by some conditions and using `has_child` statement (to specify myCompanyId). But I don't want to the result depends on existing child documents. In other words I'd like something like `LEFT OUTER JOIN` in SQL.  
Or a suitable solution is to return parent documents with no full childs but with childs which match some conditions  
Is it possible?
