```

## Additional context
Bleve analyzer use an init() function to register themselves (eg. https://github.com/blevesearch/bleve/blob/20e6eb5564e5c94478c865c6e03944882c7a886c/analysis/analyzer/keyword/keyword.go#L36-L38)

We import it through our config / command setup in the single binary, so it always started. Even if we just start one service (not using bleve).
