/**
* Convenience function for instantiating a new elasticlunr index and configuring it
* with the default pipeline functions and the passed config function.
*
* When using this convenience function a new index will be created with the
* following functions already in the pipeline:
*
* 1. elasticlunr.trimmer - trim non-word character
* 2. elasticlunr.StopWordFilter - filters out any stop words before they enter the
* index
* 3. elasticlunr.stemmer - stems the tokens before entering the index.
*
*
* Example:
*
* var idx = elasticlunr(function () {
* this.addField('id');
* this.addField('title');
* this.addField('body');
*
* //this.setRef('id'); // default ref is 'id'
*
* this.pipeline.add(function () {
* // some custom pipeline function
* });
* });
*
* idx.addDoc({
* id: 1,
* title: 'Oracle released database 12g',
* body: 'Yestaday, Oracle has released their latest database, named 12g, more robust. this product will increase Oracle profit.'
* });
*
* idx.addDoc({
* id: 2,
* title: 'Oracle released annual profit report',
* body: 'Yestaday, Oracle has released their annual profit report of 2015, total profit is 12.5 Billion.'
* });
*
* # simple search
* idx.search('oracle database');
*
* # search with query-time boosting
* idx.search('oracle database', {fields: {title: {boost: 2}, body: {boost: 1}}});
*
* @param {Function} config A function that will be called with the new instance
* of the elasticlunr.Index as both its context and first parameter. It can be used to
* customize the instance of new elasticlunr.Index.
* @namespace
* @module

* 2. boolean model chosing, user could choose which boolean model to use for each field.
* 3. token expandation, user could set token expand to True to improve Recall. Default is False.

* Query time boosting must be configured by field category, "boolean" model could be configured

* will overwrite global configuration.
* Token expand could be configured both by field category or golbally. Local field configuration will
