Uses MongoDB's Atlas Search to search hundreds of thousands of Venmo transactions. Made for dev.to's mongodb hackathon

I built this to explore using MongoDB's Atlas Search as an alternative to ElasticSearch for full text search. I used Venmo data because

1. it's public
2. users are forced to leave a text "comment" for every transaction

Production

1. Go to https://reidjs.github.io/venmo-search-frontend/
2. Type a query

Local Development

1. Start backend https://github.com/reidjs/venmo-search-server
2. Start frontend with npm run dev
3. Open browser to localhost:8000

Venmo dataset from https://github.com/sa7mon/venmo-data

• Out of the 7,000,000 transactions, I only used about 342,000 venmo transactions (free tier Mongo Atlas)
• To decide which transactions went into the database, I 'ranked' each transaction according to how long the comment was. Longer comment = more likely to be in database.

Looped through 7 million records to calculate the score on each one This nearly set my 2.6GHZ 6Core i7 32GB MBPro on fire In hindsight maybe I should have calculated a virtual field w/ mongoose, but this was the easy, dumb way of doing it. After about an hour I had at least 500,000 scores calculated, which was a big enough dataset to load into atlas
