Won't work with some words

[pgn-vole]

It seems that some words cannot get matched.

Here is how to reproduce:

 var index = lunr(function () {
    this.field('title', {boost: 10})
    this.ref('id')
  })

index.add({
    id: 1,
    title: 'Just What'
  })

index.search('Just') // []  

By replacing "Just" with an other word it seems to work fine.

Both of those words are considered stop words by lunr and are filtered out. This means they don't appear in the index and are stripped from searches.

Stop words are removed because they are very common and usually contribute little to differentiating one document from another, this helps keep the index size down and improves query performance.

If you really need to search for words that are stop words you can remove the stop word filter like so:

index.pipeline.remove(lunr.stopWordFilter)

Alternatively you can generate your own stop word filter that is more specific to your use case:

var myStopWordFilter = lunr.generateStopWordFilter(['your', 'stop', 'words', 'here'])
index.pipelline.before(lunr.stopWordFilter, myStopWordFilter)
index.pipeline.remove(lunr.stopWordFilter)
