在同一个页面下面有一个github repo的例子。这里有一个指向有问题的代码的深层链接：

您可以将ais-config嵌套在ais-index组件下进行第二次搜索。类似于：

<ais-instant-search
        :search-client="searchClient"
        index-name="instant_search_price_desc"
      >
        <ais-search-box v-model="query" />
        <ais-configure
          :restrictSearchableAttributes="['name']"
          :hitsPerPage="8"
        />
        <ais-hits>
          <template slot="item" slot-scope="{ item }">
            <h3><ais-highlight :hit="item" attribute="name" /></h3>
            <img :src="item.image" />
          </template>
        </ais-hits>
        <hr />
        <ais-index :search-client="searchClient" index-name="instant_search">
          <ais-configure
           :restrictSearchableAttributes="['name']"
           :hitsPerPage="2"
          />
         <ais-hits>
            ...
