vue.js - Vuetify Autocompletes: How to search for multiple attributes of the object?

Question

Vue code:

<template>
  <div>
    <v-card
      color="grey darken-2"
      dark
    >
      <v-card-text>
        <v-autocomplete
          spellcheck="false"
          v-model="model"
          :items="items"
          :loading="isLoading"
          :search-input.sync="search"
          @change="search=''"
          color="white"
          hide-no-data
          hide-selected
          clearable
          item-text="CodeAndName"
          item-value="Code"
          placeholder="Search stock symbols and names"
          prepend-icon="mdi-account-search"
          return-object
          autofocus
          dense
        >
          <template v-slot:item="{ item }">
            <v-list>
            <v-list-item-title class="justify-center">{{item.Code}}</v-list-item-title>
            <v-list-item-subtitle>{{item.Name}}</v-list-item-subtitle>
            <v-list-item-subtitle>{{item.Exchange}}</v-list-item-subtitle>
            </v-list>
          </template>
        </v-autocomplete>
      </v-card-text>
      <v-divider></v-divider>
    </v-card>
    <Chart v-if="model" :exchangeCode="model.Exchange" :symbol="model.Code"/>
  </div>
</template>

JS code:

import Chart from './GChart.vue'
export default {
  name: "Search",
  components: {
    Chart,
  },
  data: () => ({
    symbolsExchangesNames: [],
    isLoading: false,
    model: null,
    search: null
  }),

  computed: {
    items () {
      return this.symbolsExchangesNames
    }
  },
  methods: {
    fetchData() {
      if (this.isLoading && this.model) return
      this.isLoading = true
      this.model = null
      this.symbolsExchangesNames = []
      let hostname = window.location.hostname
      fetch(`http://${hostname}/backend/search/${this.search}`)
        .then(res => res.json())
        .then(res => {
          for(let i of res){
            this.symbolsExchangesNames.push({
              Code: i.Symbol,
              Exchange: i.Exchange,
              Name: i.Name,
              CodeAndName: `${i.Symbol} ${i.Name}`
            })
          }
        })
        .catch(err => {
          console.log(err)
        })
        .finally(() => (this.isLoading = false))
    },
    fetchDebounced() {
      clearTimeout(this._timerId)
      this._timerId = setTimeout(() => {
        this.fetchData()
      }, 200)

    }
  },
  watch: {
    search (val) {
      if(val == null || val == "") return
      if(this.model){
        if(val == this.model.CodeAndName) return
      }
      this.fetchDebounced()
    },
  }
}

As you can see in the item-text property of the autocomplete component, I'm passing "CodeAndName" which is an attribute I made so that it would search for both Code and Name of the item. This means it will show both in the search bar after a selection is made. However I want it to show only name, while searching for both code and name. I have tried passing an array into item-text but that didn't work either. I also don't know what item-value is for, the docs don't specify.

Also I don't know if this matters, but when the API is called, it will return the first 10 results where

if searchterm in item.Code or searchterm in item.Name

As mentioned in docs You can define your custom filter method like

  customFilter (item, queryText, itemText) {
      const textOne = item.CodeAndName.toLowerCase()
      const searchText = queryText.toLowerCase()

      return textOne.indexOf(searchText) > -1 
  }

and pass it in
 <v-autocomplete
     spellcheck="false" 
     :filter="customFilter"
...
</v-autocomplete>
