# Methods

# setCollection

Set/replace the entire collection of documents. If no index is provided, one will be generated. Example:

const fruits = ['apple', 'orange']
const fuse = new Fuse(fruits)

fuse.setCollection(['banana', 'pear'])

# add

Adds a doc to the collection. Example:

const fruits = ['apple', 'orange']
const fuse = new Fuse(fruits)

fuse.add('banana')

console.log(fruits.length)
// => 3

# remove

Removes all documents from the list which the predicate returns truthy for, and returns an array of the removed docs. The predicate is invoked with two arguments: (doc, index). Example:

const fruits = ['apple', 'orange', 'banana', 'pear']
const fuse = new Fuse(fruits)

const results = fuse.remove((doc) => {
  return doc === 'banana' || doc === 'pear'
})

console.log(fruits.length)
// => 1

console.log(results)
// => ['banana', 'pear']

# removeAt

Removes the doc at the specified index. Example:

const fruits = ['apple', 'orange', 'banana', 'pear']
const fuse = new Fuse(fruits)

fuse.removeAt(1)

console.log(fruits)
// => ['apple', 'banana', 'pear']

# getIndex

Returns the generated Fuse index. Example:

const fruits = ['apple', 'orange', 'banana', 'pear']
const fuse = new Fuse(fruits)

console.log(fuse.getIndex().size())
// => 4
