Meteor.js: having multiple subscriptions on one collection enforce storage results in one local collection(Workarounds?) - meteor

Question

Is there a way to store subscriptions of the same server collection in a different minimongo collection?
If not is there any best practice to work around?
I do have a summary table having 50k datasets with a lot of details in the documents.
// Server
var collection = new Meteor.Collection("collection");
Meteor.publish("detail", function (id) {
return collection.find({_id: id});
});
// A pager that does not include the data (fields:{data:0})
Meteor.publish("master", function (filter, sort, skip, limit) {
return collection.find({name: new RegExp("^" + filter + "|\\s" + filter, "i")}, {limit: limit, skip: skip, sort: options, fields: {data: 0}});
});
// Client
var collection = new Meteor.Collection("collection");
Deps.autorun(function () {
Meteor.subscribe("master",
Session.get("search"),
Session.get("sort"),
Session.get("skip"),
Session.get("limit")
);
Meteor.subscribe("detail", Session.get("selection"));
});
Problem above: both subscriptions are feed into the same collection.
This does not work well if the results of the finds are stored in the same local collection.
Having a local collection with the name of the subscription/publish would be great.
// Client
var detail = new Meteor.Collection("detail"),
master = new Meteor.Collection("master");
Any Ideas?

If you want your client side collection to have a different name from the server side collection you can not just return a collection cursor. This can be done in the publish function though like this:
Meteor.publish("details", function (id) { //details here matches the subscribe request
var self = this;
self.added( "details", id, collection.findOne({_id: id}); //details here tells the client which collection holds the data
self.ready();
});
This will not be reactive but can be made that way by using observe as in the counts by room example at http://docs.meteor.com which is explained in detail here How does the messages-count example in Meteor docs work?.
While this answers your question of how to get a specific name for a collection without having that collection on the server. I think you probably get what you want more easily with a publish function more like this:
Meteor.publish("master", function (filter, sort, skip, limit, id) {
return [
collection.find({name: new RegExp("^" + filter + "|\\s" + filter, "i")}, {limit: limit, skip: skip, sort: options, fields: {data: 0}})
, collection.find( id , {fields: {data: 1}} )
];
});
Then subscribe on client:
Deps.autorun(function () {
Meteor.subscribe("master",
Session.get("search"),
Session.get("sort"),
Session.get("skip"),
Session.get("limit"),
Session.get("selection")
);
});
Then even though all your data is in one collection you can have a reactive cursor to your selected id with the data included. Query from the client like this:
collection.find( Session.get("selection") );
