Oktavia

version:	1.0

Synopsis

Oktavia is a full text search engine for JavaScript environment. It uses FM-Index.

Usage

See following pages:

English Site: http://oktavia.info Japanese Site: http://oktavia.info/ja/

Basic Structure

oktavia command generates JavaScript file(searchindex.js) that includes index and search runtime.

HTML includes the following files:

• jquery.js : jQuery
• oktavia-jquery-ui.js : JS UI code. that loads searchindex.js and invokes runtime.
• searchstyle.css : Style file for JS UI.

When the web page is loaded, oktavia-jquery-ui.js reads searchindex.js asynchronously as WebWorker (because some index file is big to load synchronously). oktavia-jquery-ui.js calls search runtime and shows results.

Current Status

It can work as the search engine.

Now it is an alpha version. Not optimized yet.

I am planning to implement following features:

• Word Splitter option
  • Standard
  • CJK
• Index Generator
  • CSV (column, line)
  • reST (sections, paragraph, code-block, etc...)
• Custom schema support

Development

JSX

Don't be afraid JSX If you have an experience of JavaScript, you can learn JSX quickly.

• Static type system and unified class syntax.
• All variables and methods belong to class.
• JSX includes optimizer. You don't have to write tricky unreadalbe code for speed.
• You can use almost all JavaScript API as you know. Some functions become static class functions. See reference.
