<section>
<p>Convenience function for instantiating a new lunr index and configuring it with the default pipeline functions and the passed config function.</p>
<p>When using this convenience function a new index will be created with the following functions already in the pipeline:</p>
<p>lunr.StopWordFilter - filters out any stop words before they enter the index</p>
<p>lunr.stemmer - stems the tokens before entering the index.</p>
<p>Example:</p>
<pre><code>var idx = lunr(function () {
this.field('title', 10)
this.field('tags', 100)
this.field('body')
this.ref('cid')
this.pipeline.add(function () {

</header>
<section>
<p>lunr.Pipelines maintain an ordered list of functions to be applied to all tokens in documents entering the search index and queries being ran against the index.</p>
<p>An instance of lunr.Index created with the lunr shortcut will contain a pipeline with a stop word filter and an English language stemmer. Extra functions can be added before or after either of these functions or these default functions can be removed.</p>
<p>When run the pipeline will call each function in turn, passing a token, the index of that token in the original list of all tokens and finally a list of all the original tokens.</p>
<p>The output of functions in the pipeline will be passed to the next function in the pipeline. To exclude a token from entering the index the function should return undefined, the rest of the pipeline will not be called with this token.</p>
<p>For serialisation of pipelines to work, all functions used in an instance of a pipeline should be registered with lunr.Pipeline. Registered functions can then be loaded. If trying to load a serialised pipeline that uses functions that are not registered an error will be thrown.</p>
<p>If not planning on serialising the pipeline then registering pipeline functions is not necessary.</p>
