haystack (type: Array)

Array of objects containing the search list.

---

[keys] (type: Array, default: [])

List of properties that will be searched. This also supports nested properties.

---

[options] (type: Object)

Object with options that will configure the search. Scroll/Swipe down to see more information on what options are available.

---

<needle> (type: String, default: '')

The string to Fuzzy Search on.

Options

caseSensitive (type: Boolean, default: false)

Indicates whether comparisons should be case sensitive.

sort (type: Boolean, default: false)

When true it will sort the results by best match (when searching for abc in the search set ['a__b__c', 'abc'] it would return abc as the first result).

When false it will return the results in the original order.
