Question

I have a chat CouchDB which stores records with following format.

    type:"chat",
    email:"[e-mail]",
    friendEmail:"[e-mail]",
    time: [year,month,date,hour,min,sec];
    msg:"I'm very good",

I’ve created a view like this

function(doc) {
    if(doc.type==="chat" && doc.email && doc.friendEmail){
        emit([doc.time,doc.email],doc); 
    }
}

My questions is how I can get if I want only chat logs by email “[e-mail]”?

Side note: I’m using Cradle & NowJS.

Answer 1

The view you’ve created allows you to retrieve by time (and rows with the same time will be ordered by email).

To create a view that allows lookup by email;

emit(doc.email, doc);

and then query with

?key=[e-mail]

Note: In neither case is it necessary to copy the whole document into the view. You could instead do emit(key, null) and add &include_docs=true to your query.
