Better handling of English contractions in lunr.
lunr.contractionTrimmer = function (token) {
return token.replace(/('ve|n't|'d|'ll|'ve|'s|'re)$/, "")
}
lunr.Pipeline.registerFunction(lunr.stopWordFilter, 'contractionTrimmer')
var englishContractions = function (idx) {
idx.pipeline.after(lunr.trimmer, lunr.contractionTrimmer)

Lunr full text search on facets for faceted search

So many of your fields look like tags or facets, e.g. sector or market, so you full text search might not be the best way to search on these.

Instead if you had full text search on the tags themselves, e.g. full text search on all the possible values for sector or market, and then, with the resuts of this tag lookup, go and find companies that have this tag. The facted search, lookup by tags (or groups of tags) isn't really lunr's forte, but you could certainly use it for full text search of the tags.

var idx = lunr(function () {
  this.ref('id')
  this.field('name')
})

Getting started with lunr

Getting Started with Lunr

There are two ways to use lunr to index some documents, The simplest way is to just build the index client side each time the page is loaded. search.js shows an example of this.

If your data is relatively static it might be more efficient to generate the index server side and then load this on each page load, your can see an example of generating the index in node in builder.js.

You can load a serialised index like this:

var idx = lunr.Index.load(JSON.parse(json_string))
