Fetch related documents from Custom Function

[mganeshs <mg...@live.in>]

Is there a easy possibility of reading the few field from related documents
from Custom function ? 

For ex, Project document contains, project id, project name, Project manager
id  ( which is nothing but employee id ). & Employee document contains field
( Employee id, Employee name ). Now while querying the Project documents, in
a custom function want to pass project manager id, and would like to read
employee document of that Project manager and return employee name of that
project manager. 

WE can do Join, but for various reason, for me Join won't work. So would
like to read the employee document from the custom function. As Custom
function is getting executed inside SOLR, what's the easy to read the other
documents in SOLR, instead of establishing new connection via solrj and read
it.

Thanks in advance.

Solr Experts, any easy way for reading other solr docs ( other docs ) from
solr custom function ?

Yes. But being inside solr ( I mean code getting executing via Custom
function ), do we have option to read the other solr documents in a easy
way.

Hello,
It sounds either like classic denormalization or (little bit slow and
cumbersome) result transformer [subquery].
