How can I search numerals and numbers in the same way?

Algolia's search engine does not have settings to treat numerals and numbers in the same way (for example, searching for "iPhone 13" using the query "iPhone thirteen"). Therefore, the basic strategy is to create synonyms for these expressions.

We have a public repository with CSV versions of such files, which you can find here.
 
Then, you can import synonyms by uploading the CSV file to any Algolia indices you'd like, by following this documentation.
