There are no other configuration options for the legacy tokenizer. All
normalization functions are hard-coded.

#### Token Analysis
##### Postcode token analyzer
The analyzer `postcodes` is pupose-made to analyze postcodes. It supports
-a 'lookup' varaint of the token, which produces variants with optional
+a 'lookup' variant of the token, which produces variants with optional
spaces. Use together with the clean-postcodes sanitizer.
The analyzer cannot be customized.
