<div class="spec-same" v-for="one in booklist | conditions"> 

filters:{
    conditions: function(items){
        var searchRegex = new RegExp(this.booksearchtext, ‘i‘);
        var arr=[];
        for(var i= 0, j = items.length; i < j; i++){
            arr[i] = {};
            arr[i].contacters = [];
            for(var item = 0, len = items[i].contacters.length; item < len; item++){
                if(searchRegex.test(items[i].contacters[item].name) || searchRegex.test(items[i].contacters[item].enterpriseName) || searchRegex.test(items[i].contacters[item].phoneNumber) || searchRegex.test(items[i].contacters[item].uniqueID)){
                    arr[i].firstLetter = items[i].firstLetter;
                    arr[i].contacters.push(items[i].contacters[item]);
                }
            }
        }
        return arr;
