Search & Filtering [feature request]

Hi, thanks for sharing this!
I'm new to Apollo and Graphcool and wonder if it would be possible to include a good example of implementing some complex search and filtering:

1. Search posts (in title and description) + search results page.
2. Filter posts by multiple criteria, e.g. get all posts where:
   "createdAt" is between Date_A and Date_B and have "tags" in [ tag1, tagt2, tagt3... ] and made by "users" [ user1, user2...] etc.
