Fuse.createIndex

Use Fuse.createIndex to pre-generate the index from the list, and pass it directly into the Fuse instance.

const list: MyType[] = [myType1, myType2, etc...]

const index = Fuse.createIndex<MyType>(
 keys: ['key1', 'key2']
 list: list
)

const options: Fuse.IFuseOptions<MyType> = {
 keys: ['key1', 'key2']
}

const myFuse = new Fuse(list, options, index)

::: tip For very large datasets, especially those with large strings, consider pre-generating the index with Fuse.createIndex. This will speed up instantiation. :::
