设置索引库结构，给用户添加可自动补全的suggestion,并将一些字段变成集合放到suggestion里面去

若business有多个值，可进行切割

进行切割

 //将brand 和 business 变成集合放到suggestion里
        if(this.business.contains("/")){
            //business有多个值，需要切割
            String[] arr = this.business.split("/");
            //添加元素
            this.suggestion = new ArrayList<String>();
            Collections.addAll(this.suggestion,arr);
        }else
            this.suggestion = Arrays.asList(this.brand,this.business);

切割成功
