The allowTyposOnNumericTokens parameter controls whether Algolia applies typo tolerance to numbers. Allowing typos can broaden results but may lead to irrelevant matches. Turning typo tolerance off on numbers helps enforce precision, especially for data like:
  • Postal or product codes
  • Identifiers
  • Phone numbers
For more information, see typo tolerance and numbers.

Examples

​
Turn off typos on numbers by default
