How to create client side full text search engine with pure JavaScript and HTML5?

Question

I need to create client side search engine for an offline html application in offline storage like CDROM. I already create it with Win32 and the catalog file is near 2GB (MDB file).

My offline web application use CEF (Chromium Embedded Framework) and PhoneGAP so I can disable the browser web security. I thought the IndexedDB may help me but , I couldn't find anyway to copy the storage file to other media.

1. My catalog file will be near 2GB, so I can't read all record to memory.
2. I need to make the output media cross-platfrom with PhoneGAP, so I can't use activeX objects for final search. Also I can disable web security restriction by that tools.
3. I can create the catalog file and media with any windows application. the key note that the output file that query the catalog should be be pure JavaScript.

Is there any HTML5 big storage system available (I can disable web security by PhoneGAP) to create offline HTML application search catalog that can be copied to other removable media?

During last september Paris JS, he did a presentation of the concepts behind : http://kornr.net/prez/paris.js22/#/
