Tech Stack

This search experience is powered by Typesense which is a blazing-fast, open source typo-tolerant search-engine. It is an open source alternative to Algolia and an easier-to-use alternative to ElasticSearch.

This demo uses a geo-distributed 3-node Typesense cluster running on Typesense Cloud, with nodes in Oregon, Frankfurt and Mumbai.

Repo structure

• src/ and index.html - contain the frontend UI components, built with Typesense Adapter for InstantSearch.js
• scripts/ - contains the script to index the data into Typesense.
• data/ - contains a 1K sample subset of the HN comments dataset. But you can download the full dataset from the Google BigQuery marketplace.
