Search does not seem to work for tags with emoji

AFAIK it’s only because the regex we have here:

lib/search.rb

main


      
          end
          
          advanced_filter(/\Ain:unseen\z/i) do |posts|
            if @guardian.user
              posts.joins(
                "LEFT JOIN post_timings ON
                  post_timings.topic_id = posts.topic_id
                  AND post_timings.post_number = posts.post_number
                  AND post_timings.user_id = #{ActiveRecord::Base.connection.quote(@guardian.user.id)}
                ",
              ).where("post_timings.user_id IS NULL")
            end
          end
          
          advanced_filter(/\Awith:images\z/i) { |posts| posts.where.not(posts: { image_upload_id: nil }) }
          
          advanced_filter(/\Acategor(?:y|ies):(.+)\z/i) do |posts, terms|
            category_ids = []
          
            matches =
              terms

is not allowing emojis. If this was matching on emoji, it would work after.

We might want to consider using something like: GitHub - ticky/ruby-emoji-regex: 💎 A set of Ruby regular expressions for matching Unicode Emoji symbols. · GitHub to have a good emoji regex.

what do you think @sam ?
