Okay so apologies for taking so long to finish this, things got hectic and I completely forgot about this branch.
I changed the search ip and port in the settings file to what you used in production

Now this branch will switch the code completely over to elasticsearch even in development. For local development docker compose should be started with the command docker-compose -f docker-compose.yml -f dev.yml up.

The elastic athome4 collection index can be downloaded from https://www.dropbox.com/s/j9ym9f5zt5c0ex8/esdata.7z?dl=0 and should be placed in the data folder.

Your cc-prod way of doing things was a lot cleaner so I tried to emulate that. Now development uses env variables for search stuff as well. I added two env variables INDEX_NAME and SEARCH_ENGINE so we can switch between the two search engines. Their defaults are elastic and commoncrawl so you won't need to change anything in production.

You can witch between engines with the commands docker-compose -f docker-compose.yml -f ./dev/dev_anserini.yml up and docker-compose -f docker-compose.yml -f ./dev/dev_elastic.yml up
