To use this, set up a .env file with the following fields:

OPENSEARCH_INITIAL_ADMIN_PASSWORD=anything
OPENSEARCH_HOST=localhost
OPENSEARCH_PORT=9200
POSTGRES_DB=postgres
POSTGRES_USER=postgres
POSTGRES_PASSWORD=anything
POSTGRES_HOST=localhost
POSTGRES_PORT=5432

Then, run query.py and pass the search term as a command line argument. As we include more of the query specification, those will either be other command line arguments or we can find another way to do this.
