Indexing and searching bookmarked memes

[dennyabrain]

We need to create a flexible and powerful searching mechanism for the memes.
For every meme we bookmark, we'll have searchable data of this shape

post : {
  title : // this is an optional text user enters to describe their memes
  platform : // instagram, twitter, tiktok, youtube etc
  tags : [] // array of strings added by a user
  annotation : {
  } // a free form key value pairs. it could have any keys. 
  platform_metadata : {
  } // a free form key value pairs. this is metadata we scrape from the platform itself. so for instagram, it might involve the caption and location but for tweets it might involve a hashtag in the tweet.
}

We should be able to search for any of these fields.
searching for the top level fields like title, platform, tags would be easy with elasticsearch.
I want our server to also support complex queries for annotation and platform_metadata. So for instance we should be able to pass a query string like "?platform_metadata.caption=cat" and it should return all matching memes with cat in their caption.

You'll have to create two API endpoints /index and /search.
