Nested Object Inverted Search Engine

This is a native library meant to be linked into other projects and will expose a C API.

It's a full text index and query system that understands the semi structured nature of JSON, and will allow:

• Stemmed word/fuzzy match
• Case sensitive exact word and sentence match
• Arbitrary boolean nesting
• Greater than/less than matching

Storage backends

The search engine is generic over its storage backend. The reference backend is RocksDB, provided by the noise-storage-rocksdb crate, which also ships a repl-rocksdb example (run it with cargo run --example repl-rocksdb -p noise-storage-rocksdb).

A backend is any type implementing the traits in the noise-storage crate: BackendDatabase, BackendBatch, BackendSnapshot and CursorBackend. To
plug in your own, implement those traits in your own crate and use the generic engine types directly, with no changes to this repository:

use noise_search::index::{Index, OpenOptions};

let mut index = Index::<MyBackend>::open("mydb", Some(OpenOptions::Create))?;

The engine crate noise_search depends only on noise-storage.
