Test async-index-and-search with two service workers

[eklem]

One for indexing and one for searching?

• Make two json-files to be indexed. One small to index first and then one big that can be indexed while the user searches within content in the first one.
• A service worker for the indexing part and a service worker for the query part
• Make two html files so you can click back and forth and still get info on how indexing is going, i.e. a message for every 1000 documents indexed.

@fergiemcdowall Service workers looks interesting.

• As web workers, they don't block the UI when doing processor heavy stuff, like indexing
• For a site (or a part of a site / domain) they can run in the background even if you switch pages.
• They can pull stuff from cache if up to date instead of using network. This means true offline applications

I was thinking I should test that it can actually work, and then maybe make a library for service workers for search-index when v2.x.x is out.

With this we can make a offline-first and the basis for non-blocking UI for search-index, and have it framework agnostic. So easier to make a browser application and still your choice of what to use to develop the application.

Seems only one service worker can be added to an app for what my purposes are:

Seems the idea is to add the possibility of running a worker / sharedWorker from a service worker, but not implemented yet.

Hmm, seems it might actually be possible??? Will try

@eklem yes, very interesting!

I'll explore =) If it works out, it could maybe take JSON input and give JSON output as a browser version of Norch.
