Filtered results in Meteor

example.coffee

# Server
Meteor.publish 'foo', (searchQuery) ->
  return Foo.find
    bar: searchQuery

# Client
Meteor.subscribe 'foo', Session.get 'searchQuery'

# {#each foo} in your template and then to update:
Session.set 'searchQuery', 'some new query'

for-the-weak.js

Meteor.publish('foo', function(searchQuery) {
  return Foo.find({
    bar: searchQuery
  });
});

Meteor.subscribe('foo', Session.get('searchQuery'));

Session.set('searchQuery', 'some new query');

This is obviously a simple example, but it shows the basic pattern of how to tie user input to a reactive data source and have the data filtered based on changing user input.

I added a javascript version for those who have difficulty reading the efficiency of coffeescript! ;-)
