搜索应将特殊字符与其“常规”等效字符匹配

这与搜索索引无关。对于精确匹配，我们会将其与 Post#raw 和 Topic#title 进行比对：

              # A is for title
              # B is for category
              # C is for tags
              # D is for cooked
              weights = @in_title ? 'A' : (SiteSetting.tagging_enabled ? 'ABCD' : 'ABD')
              posts = posts.where(post_number: 1) if @in_title
              posts = posts.where("post_search_data.search_data @@ #{ts_query(weight_filter: weights)}")
              exact_terms = @term.scan(Regexp.new(PHRASE_MATCH_REGEXP_PATTERN)).flatten
          
              exact_terms.each do |exact|
                posts = posts.where("posts.raw ilike :exact OR topics.title ilike :exact", exact: "%#{exact}%")
              end
            end
          end
          
          @filters.each do |block, match|
            if block.arity == 1
              posts = instance_exec(posts, &block) || posts
            else
              posts = instance_exec(posts, match, &block) || posts
            end
