Issue with typo tolerance & barcode search

Hi, I would like to use instantSearch to search by barcode. But I have a problem with the results, which also give us products with a barcode close to the one we’re looking for.

I’ve added the barcode attribute to disableTypoToleranceOnAttributes and disablePrefixOnAttributes lists on our Algolia search config, but it doesn’t seem to work, and I always get several results when I search for a barcode, when there should only be one.

And I have the same problem when using the search directly on my Algolia dashboard.

Do you have any idea where the problem might be coming from ?
