// put(docText, docId)
index.put("hey-you", 1);
//> 2
 
index.put("hey you me", 2);

//> [2]
 
index.search("hey");
//> [1, 2]

Providing your own tokenizer.

The tokenizer is used during put and search methods.

Development

Clone it :)

I'm using es6->es5 via babel, and polyfilling in Set and Map.

Run gulp for the es5 translation.

npm test for running the tests.
