Any field type which has its value stored as a string can have a "Sortified" version which will make sorting case-insensitive and ignore punctuation.
sortify: true creates a parallel
Sortified version of the field that is more intuitive for sorting purposes. Apostrophe will automatically use it if a request is made to sort on the original field.
For instance, if your field's
lastName and you set
lastNameSortified will automatically be created and used when sorting on the
lastName field. This provides case-insensitive sorting that also ignores punctuation differences.
