Easy fix: search only works with ASCII characters

[piskov]

Ruby’s \w is basically [a-zA-Z0-9_] which is useless for many languages.

Thus the following code ↓ inside searchable.rb means search won’t work for extended latin, greek, cyrillic, what have you

        def remove_invalid_search_characters(terms)
          terms.gsub(/[^\w"]/, " ") // ***********************←
        end

        def quote_query_tokens(terms)
          terms.scan(/"[^"]*"|\w+/) // ***********************←
            .filter_map { |token| token.delete('"').presence }
            .map { |token| %("#{token}") }
            .join(" ")
        end

Replace it with [[:word:]] and this should fix it according to the benevolent AI (I don’t know shit about RoR)
