我在fos_elastica.yaml中遇到带有配置的排序字段问题。我的配置像:

我如何忽略隐式转让？

Answer 1

根据Wikipedia on the Norwegian alphabet

The letter Å (HTML å) was introduced in Norwegian in 1917,replacing Aa or aa.
[...]
Family names may not follow modern orthography, and as such retain the digraph aa where å would be used today.

更具体地说是关于归类的主题

Aa is treated like Å in alphabetical sorting, not like two adjacentletters A, meaning that while a is the first letter of the alphabet,aa is the last.

您的排序顺序工作正常。
