Description

In August, I made some changes to the elasticsearch schema and query structure to try and improve query latency (aka, speed and performance). Kept a log of notes on these experiments here: https://github.com/internetarchive/fatcat-scholar/blob/master/notes/scaling_works.md

These should be reviewed and revisited as we move towards broad release. In particular, more quantitative measurements would be nice to have, and it seems like index_phrases may have had a significant increase in disk utilization (50%? memory is fuzzy) with small or no latency improvement.

Contributor guide

Research direction
Analyze the impact of the index phrases setting on disk usage and query latency by running benchmarks against the existing Elasticsearch schema.
