Question about result

[mikeerickson]

I am giving this module a try, but I am having some difficulty understanding the results. I am sure this is pilot error, so if you could enlighten me on what is actually happening, it will help me better understand.

In the following example, the results are listed at the bottom. Specifically, when providing a search term of "Kira ABC", I am "expecting" results to include all three items, when in fact it is only return the last two items (associated to Kira) but omitting the first one (associated to ABC)

If I do a second query of "ABC Kira" it does return the expected rows which leads to my confusion and needing more information.

• If I search "Kira ABC" it only returns contact.firstName === 'Kira'
• If I search "ABC Kira" it returns both title starts with "ABC" AND contact.firstName === 'Kira'
• If I adjust the threshold to something like 0.75 then the results do indeed change, but it also includes an item that is definitely not part of the search value (see Result 2 and inclusion of Another Company)

Again, I am sure this is pilot error, but I cant seem to find anything in the documentation which documents the order and precedence of queries.

And, I am not able to find anything which documents what refIndex value indicates

const { dd } = require('dumper.js')
const Fuse = require('../dist/fuse')

const customerList = [
  {
    title: 'ABC Company',
    contact: { firstName: 'Mike', lastName: 'Erickson' }
  },
  {
    title: 'Another Company',
    contact: { firstName: 'Mike', lastName: 'Erickson' }
  },
  {
    title: 'XYZ Company',
    contact: { firstName: 'Kira', lastName: 'Erickson' }
  },
  {
    title: 'Foobar Company',
    contact: { firstName: 'Kira', lastName: 'Erickson' }
  }
]

const setup = (itemList, overwriteOptions) => {
  const list = itemList || []
  const options = { ...{}, ...overwriteOptions }

  return new Fuse(list, options)
}

let fuse = setup(customerList, {
  score: true,
  keys: ['title', 'contact.firstName']
})

let result = fuse.search('Kire ABC')

@mikeerickson refIndex is the index of the item on the index object. Try pre-indexing with Fuse.createIndex instead of letting Fuje.js do it behind the scenes.
