Improve filter regex

[rostixman]

What would you like to be able to do? Can you provide some examples?

I would like to be able to pass filter attribute in French, German, or other languages. Because now regex doesn't allow non-Latin characters.

In my case I have Mobility gem and want to search in other languages. I found solution with custom search method, but in my case it's enough to add this:

COLLECTION_FILTERS = {
    name: -> (resources, attr) { resources.search(attr) }
  }.freeze

and also I add search method to resource model with the logic that I need:

scope :search, -> (name_q) do
    i18n do
      name.lower.matches("%#{name_q&.downcase}%")
    end
  end

How could we go about implementing that? Switch \w to Unicode codes/ranges or word.match?(/^#{filter}:.*$/) but this way may be unsafe

Can you think of other approaches to the problem? Allow custom regex for filter attribute

OK, so if I'm understanding correctly, the issue is with the following code, right?

https://github.com/thoughtbot/administrate/blob/5c278d7b38bde0db69e27779465fd4c99c8dc3ae/lib/administrate/search.rb#L33-L35

You are right that it should support Unicode. Do you want to provide a PR to fix it? :slightly_smiling_face:
