Elasticsearch is too dumb. You need to use a parser and build a syntax tree to have a good representation of the code base. That's what facebook and google do on their java code.

Agree that any small to medium company could have a mono repo without special tooling. Yet they don't.

There are companies that care about development and there is the rest of the world.

Github uses Elasticsearch [1]. I agree that ES is too dumb by default, however the analysis pipeline can be customized for searching source code.
