It is the service that most directly executes a search query. It does this by
evaluating a low-level query, and then using the index to find the documents
that match the query, finally ranking the results and picking the best matches.

## Central Classes
* [IndexService ](src/main/java/nu/marginalia/index/IndexService.java ) is the REST entry point that the internal API talks to.
* [IndexQueryService ](src/main/java/nu/marginalia/index/svc/IndexQueryService.java ) executes queries.
* [SearchIndex ](src/main/java/nu/marginalia/index/index/SearchIndex.java ) owns the state of the index and helps with building a query strategy from parameters.

* [IndexResultValuator ](src/main/java/nu/marginalia/index/results/IndexResultValuator.java ) determines the best results.

* [features-index/index-forward ](../../features-index/index-forward/ )
* [features-index/index-reverse ](../../features-index/index-reverse/ )
