Here's the backstory.

Let's say you have a static web site and you want to provide a search via a pre-populated search index. So you write a little program to read in the content of your site and create some search indices. We can use Bleve and utilize its in-memory store since it doesn't rely on os-specific functionality like mmap.

package main

import "github.com/blevesearch/bleve"

func createIndex(idx bleve.Index) {
	//Some code for walking the website and populating the index...
}

func main() {
	index, _ := bleve.NewMemOnly(bleve.NewIndexMapping())
	createIndex(index)
	// The Bleve store is now populated with your sites search indices...
	// ... now what?
}

Given the above pseudocode, being ran with GopherJS, to create the search indices, is there a way to serialize it to a file so it can be pulled in by the website? The above link shows ways to use GopherJS to build an index using GopherJS, but I can't figure out how to use GopherJS to generate a pre-built search index.

Any help will be appreciated.
