 This repository contains crates to quickly debug the engine:
  - There are benchmarks located in the `benchmarks` crate.
+ - The `cli` crate is a simple command-line interface that helps run [flamegraph] on top of it.
+ - The `filter-parser` crate contains the parser for the Meilisearch filter syntax.
+ - The `flatten-serde-json` crate contains the library that flattens serde-json `Value` objects like elastic search does.
+ - The `helpers` crate is only used to do operations on the database.
  - The `http-ui` crate is a simple HTTP dashboard to tests the features like for real!
  - The `infos` crate is used to dump the internal data-structure and ensure correctness.
- - The `search` crate is a simple command-line that helps run [flamegraph] on top of it.
- - The `helpers` crate is only used to modify the database inplace, sometimes.
+ - The `json-depth-checker` crate is used to indicate if a JSON must be flattened.
