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

Custom request handler approach seems the most straight forward and the only one I can think of quickly.

Re: How to perform a double query in one
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. ryan Otis Gospodnetic wrote: Custom request handler approach seems the most straight forward and the only one I can think of quickly.
