If I have a document I’m storing that looks like this:

doc = {

userId: \*‘\*yoyomamma',  
physicians: [{  
name: "sanjay gupta",  
id: 403494  
},  
{  
name: "daniel litvak",  
id: 3382  
}],  
procedures: [{  
name: "appendectomy",  
id: 3939,  
date: "2/3/2012"  
}

… etc a bunch of other stuff

}

When I search on “appendectomy” I want to only return the following:  
“userId” and the matching “procedures” fields…..

Any thoughts on the best approach to do this?

thanks

phil

It somehow means to me that you are searching for procedures so you should index procedures not doc.

If you need both, you could may be use Parent/child feature so you will have different docs indexed.

My 2 cents
