Wish to have full-text search ready in Dexie

[datdinhquoc]

I found the example how to use hook to make full-text search feature: https://github.com/dfahlander/Dexie.js/blob/v1.5.1/samples/full-text-search/FullTextSearch.js

I have to load some docs from IndexedDB thru' Dexie and there's an input box. Using the function 'filter' takes too much time on large table, wish there could be built-in mechanism in Dexie to simply set some text fields to be full-text indexed, and query on them.
