If I understand the question... you essentially want a JOIN function.
Find the set of docs linked to by an initial query.
Right now, you either need to do two queries (in the client or custom
RequestHandler) OR, if possible, flatten the data into each doc. For
your specific example, can you add a field for every reference to the
referenced doc? If so, then it is a single query.

Subject: How to perform a double query in one
Hi,
Is there a way to perform 2 search queries in one search request, and
then
return their combined results?
Currently I am performing the following:
I have a document which consists of "id" field which is the unique
identifier, the "info" field, and an "xid" field which contains the ids
of
other documents (these documents are also indexed) it relates to. Thus
there
is a mapping between two or more documents thru the "xid" field.
Now, in my first search, I search for the document based on a given id,
say
XYZ on the "id" field. this gives me exactly one document and I
retrieve the
document's "xid" content.
Then I search for the same id - XYZ in the "xid" field and retrive the
"xid"
content for all the matching documents.
Can I perform the same operation in one query? If yes, how do I go
about it?
Do, I need to write my custom request handler? If no, any other
efficient
way to do the same?
Regards,
Rishabh
