How can Algolia be configured to treat an ampersand as literal character?

Question

By default, Algolia doesn't recognize ampersands as characters. For example: "K&N", "AT&T", or "PG&E" will match in search but the ampersand is not bolded (false negative), and results include those without ampersands (false positives).

You can see this behavior here: https://demo.algolia.com/instant-search-demo/?q=at%26t

Answer 1

Algolia web dashboard -> Indices -> Ranking -> Optional Words & Separators -> Separator characters to index:

Add the ampersand (&) to this field and hit Save.
