Bounty Hunter


A full text search engine of unstructured documents. It is base upon a reversed index.

Simple usage

First create an instance of cargo

Cargo storage = new Cargo(MODE: CargoMode.MEMORY);

Construct an instance of Hunter.

Hunter hunter = new Hunter( cargo );

Feed document into the system so it can be indexed.

hunter.feedDocSync( "hello world", "This is a hello world document ... fix");

You can also feed a document asynchronous and then it will use the asynchronous methods from Cargo.

hunter.feedDoc( "hello world", "This is a hello world document ... fix").then((int docId) {
	// do stuff here!

Search for a document and retrieve the documents containing these words. "document fix" );
