Vue.js Select 下拉列表中的复选框后如何清除 vautocomplete(多个)搜索输入

我有多个v-autocomplete组件来自Vuetify.当前，例如，如果在搜索输入中输入"Cali"并选中"California"值，则"Cali"值仍存在于搜索输入中.我需要清除输入的值.对于current，关闭下拉列表时搜索值已清除，但我需要在选中复选框时清除它.

<v-autocomplete
        v-model="select"
        :loading="loading"
        :items="items"
        :search-input.sync="search"
        cache-items
        class="mx-3"
        flat
        hide-no-data
        hide-details
        label="What state are you from?"
        solo-inverted
        multiple
      ></v-autocomplete>

new Vue({
  el: '#app',
  data () {
    return {
      loading: false,
      items: [],
      search: null,
      select: null,
      states: [
        'Alabama',

        'Virgin Island',
        'Virginia',
        'Washington',
        'West Virginia',
        'Wisconsin',
        'Wyoming'
      ]
    }
  },
  watch: {
    search (val) {

      val && val !== this.select && this.querySelections(val)
    }
  },
  methods: {
    querySelections (v) {

      this.loading = true
      // Simulated ajax query
      setTimeout(() => {
        this.items = this.states.filter(e => {
          return (e || '').toLowerCase().indexOf((v || '').toLowerCase()) > -1
        })
        this.loading = false
      }, 500)
    }
  }
})

在下拉列表中 Select 值后，我想清除搜索输入中的值.
