Publish selected documents from a collection


Hi everyone,

I have a collection in my MongoDB database with 60,000 documents. However, I don’t need to return them all into my application.

Here’s an example of the data

I want to be able to narrow down the results based on if the Category field contains either the word CONV or CUMWR. What I have at the moment looks like this:

Meteor.publish('statistics', function publishSomeData() {
  return statistics.find({ "Category" : /.*CONV.*/ });
  return statistics.find({ "Category" : /.*CUMWR.*/ });

In my application however, this only shows me the data containing CONV and not CUMWR.

I also tried doing this:

Meteor.publish('statistics', function publishSomeData() {
  return statistics.find({ "Category" : /.*CONV.*/ }, { "Category" : /.*CUMWR.*/ });

But again the same issue occurs.

Can any body let me know what i’m doing wrong here?

Many thanks,


Installed the smart publish package and now works like this:

Meteor.smartPublish('statistics', function publishSomeData() {
  return [
    statistics.find({ "Category" : /.*CONV.*/ }),
    statistics.find({ "Category" : /.*CUMWR.*/ })


Using $or should also work:

Meteor.publish('statistics', function publishSomeData() {
  return statistics.find({$or:[{Category : /CONV/ }, {Category : /CUMWR/ }]});


Be aware that although MongoDB tries to optimise regular expression searches on indexed fields, performance is likely to be worse than using non-regex searches.


You know yo can send a parameter to the publish function through the subscibe call?
Meteor.subscribe("docsByCategory", "CONV")

Meteor.publish('docsByCategory', function (cat) {
  return statistics.find({Category : cat });
